[0028] The present disclosure comprises a fuel cell arrangement designed to accommodate a stack of fuel cells. Fuel cells are electrochemical devices that convert the chemical energy of a fuel into electricity through a chemical reaction with an oxidant. The fuel is typically hydrogen, and the oxidant is typically oxygen. The fuel cell arrangement is designed for use in any suitable power supply application. For example, the fuel cell arrangement can be designed for automotive and non-automotive applications. The fuel cell arrangement of the present disclosure can be used to power any suitable vehicle, such as any suitable all-electric vehicle, hybrid electric vehicle, etc.Suitable vehicles include, but are not limited to, passenger vehicles, commercial vehicles, public transport vehicles, construction vehicles (and construction machinery), locomotives, watercraft, etc. With regard to non-automotive applications, the fuel cell arrangement can be designed, for example, for use as a portable generator, a mobile electric charging system, or a building generator.

[0029] The fuel cell assembly generally comprises a base, a first and second side wall mounted to the base, a wet end assembly mounted to the wet ends of the first and second side walls, a first electronics housing mounted to the dry ends of the first and second side walls, and a second electronics housing mounted to the first side wall, the second side wall, the wet end assembly, and the first electronics housing, respectively. A fuel cell housing is defined by the base, the first side wall, the second side wall, the wet end assembly, the first electronics housing, and the second electronics housing. The second electronics housing generally provides a cover for the fuel cell housing. A fuel cell stack is located within the fuel cell housing.

[0030] At least the first side wall, the second side wall, and the wet end unit are made of a non-conductive composite material. The first and second electronics enclosures may each be made of a metallic material or the non-conductive composite material. The composite material may be bonded with a shield for electromagnetic compatibility (EMC). A power sensing module is located within the first electronics enclosure, and a power conversion unit, as described herein, is located within the second electronics enclosure. Electrical connectors on the exterior of the first electronics enclosure are easily accessible so that the assembly can be connected to any suitable load. The fuel cell assembly is designed to be easily "plugged in" to provide power to any suitable application (automotive or non-automotive).

[0031] The fuel cell assembly integrates the fuel cell housing, the first electronics housing, and the second electronics into a single assembly that is easy to transport and install. The use of non-conductive composite materials for at least the side walls and the wet end unit provides the fuel cell assembly with a manageable weight, further facilitating transport and installation. The rails incorporated on the inner surfaces of each side wall are designed to interact with the fuel cell stack to facilitate the insertion of the stack and / or individual fuel cells into the fuel cell housing. The interaction between the rails and the fuel cell stack also secures the fuel cell stack in position to prevent movement of the stack and / or individual cells, such as...during the operation of a vehicle that includes the fuel cell assembly.

[0032] By forming the wet end unit from a composite material, various fluid flow channels / distributors can be integrally formed within it, thereby reducing the number of required components and connectors. The integration of the fuel cell housing, the first electronics housing, and the second electronics housing together increases the structural rigidity of the assembly, reduces its packaging size, and lowers its overall weight. This integration also reduces the number of connections and components required in the system. The fuel cell assembly of this disclosure provides a direct interface to an external plant peripheral subsystem that includes anode, cathode, and thermal management system components, thus eliminating the need for separate distributors for such connections.

[0033] Fig. 1 and Fig. Figure 2 illustrates an example of a fuel cell arrangement 10 according to the present disclosure. The fuel cell arrangement 10 generally comprises a base 20, a first side wall 30 and a second side wall 32 ( Fig. 2) The first side wall 30 and the second side wall 32 are mounted on the base 20. A wet end unit 60 is mounted at one wet end of each of the first side wall 30 and the second side wall 32. A first electronics housing 70 is mounted at one dry end of each of the first side wall 30 and the second side wall 32 and provides a dry end unit. A second electronics housing 80 is mounted at each of the first side wall 30, the second side wall 32, the wet end unit 60, and the first electronics housing 70. A fuel cell housing 110 is defined by the first side wall 30, the second side wall 32, the wet end unit 60, the first electronics housing 70, and the second electronics housing 80. The second electronics housing 80 generally provides a cover for the fuel cell housing 110. These components are mounted in any suitable manner, such as with suitable fasteners.With further reference to . Fig. 3 and Fig. 4 The fuel cell housing 110 is designed to accommodate a fuel cell stack sub-assembly 50. The fuel cell stack sub-assembly 50 comprises a plurality of individual fuel cells stacked within the fuel cell housing 110.

[0034] The first side wall 30, the second side wall 32, and the wet end unit 60 are made of any suitable non-conductive composite material. The composite material can be any suitable non-metallic material, such as any suitable polymeric material. The composite material can be reinforced in any suitable way, such as with glass fibers. Each of the base 20, the first electronics housing 70, and the second electronics housing 80 can also be made of the non-conductive composite material or of another suitable metallic material, such as aluminum. The non-conductive composite material is lighter than most metallic materials and thus provides a lower weight for the fuel cell assembly 10. The components of the fuel cell assembly 10 can be made of the same non-conductive composite material or of different non-conductive composite materials.The composite material can be combined with EMC shielding.

[0035] With renewed reference to Fig. 1 and Fig. Figure 2 defines a first groove 34 on the outer side of the first side wall 30 and a second groove 36 on the outer side of the second side wall 32. The first groove 34 and the second groove 36 are designed to accommodate any suitable wiring and function as a cable harness. Opposite the first groove 34, on the inner side of the first side wall 30, is a first rail 40, as shown, for example, in Fig. 4 and Fig. Figure 5 illustrates this. Opposite the second groove 36, a second rail 42 is located on the inside of the second side wall 32. The first rail 40 is formed rigidly with the first side wall 30, and the second rail 42 is formed rigidly with the second side wall 32. Thus, the first rail 40 and the first side wall 30 are monolithic, and the second rail 42 and the second side wall 32 are monolithic. The first rail 40 and the second rail 42 can be directly opposite each other and coplanar, or they can be offset from each other, as illustrated in Figure 5. Fig. 5.

[0036] The first rail 40 and the second rail 42 are each designed to interact with the fuel cells of the fuel cell stack subassembly 50 to limit the movement of the fuel cell stack subassembly 50 within the fuel cell housing 110. The first rail 40 and the second rail 42 also facilitate the insertion of the fuel cells into the fuel cell housing 110. For example, the fuel cells can be moved individually along the first rail 40 and the second rail 42 to stack them within the fuel cell housing 110. Alternatively, the fuel cell stack subassembly 50 can be inserted into the fuel cell housing 110 as a whole and moved along the first rail 40 and the second rail 42.

[0037] The first side wall 30 and the second side wall 32 each comprise one or more slots 46 in conjunction with pins 48. The pins 48 are connected to a support arrangement for the fuel cell stack sub-assembly 50. The interaction between the pins 48 and the slots 46 is such that the pins 48 are movable within the slots 46 to accommodate a relatively larger or smaller fuel cell stack sub-assembly 50.

[0038] The first side wall 30 defines a window 44 ( Fig. 4), which extends through the first side wall 30 and is in fluid communication with the wet end unit 60. An injector housing 120, which provides a fuel rail damping volume, is mounted on the first side wall 30 above the window 44. The injector housing 120 comprises a plurality of hydrogen injectors 122, which are designed to be coupled to any suitable hydrogen source and supply hydrogen to the fuel cell stack sub-assembly 50. With particular reference to Fig. 5 A hydrogen distributor 150 is in fluid communication with the hydrogen injectors 122 and the injector housing 120. The hydrogen distributor 150 comprises an ejector 152, which is designed to expel the hydrogen into the fuel cells of the fuel cell stack sub-assembly 50, and a non-return device 154, which prevents hydrogen backflow. A water separator 160 is located near the hydrogen distributor 150.

[0039] With reference to Fig. 1-3 and 5, outside the wet end unit 60, is a wet end manifold with a first end plate 62 and a second end plate 64. The first end plate 62 and the second end plate 64 are made of the non-conductive composite material. The first end plate 62 is mounted directly to the wet ends of the first side wall 30 and the second side wall 32. The second end plate 64 is mounted to the first end plate 62. The first end plate 62, the second end plate 64, and the wet end unit 60 define a plurality of manifolds for supplying oxygen, hydrogen, and coolant to the fuel cells of the fuel cell stack sub-assembly 50. For example, the first end plate 62, the second end plate 64, and the wet end unit 60 define an air inlet 130 for oxygen, an air outlet 132, a coolant inlet 140, and a coolant outlet 142. The coolant can be any suitable coolant, such as water. As in Fig. Figure 3 illustrates that an interface 170 for a top drain for draining water from the fuel cell stack sub-arrangement 50 is included.

[0040] With particular reference to Fig. 3. The first electronics housing 70 comprises a power sensing module 72 of the power electronics of the fuel cell assembly 10. The power electronics comprise any suitable fuel cell power electronics designed to control and regulate the operation of the fuel cell assembly 10 for power generation. The power sensing module 72 is connected to the power conversion unit 82 via a wired connection extending through a passage 90 defined between the first electronics housing 70 and the second electronics housing 80. The first electronics housing 70 further comprises electrical connectors 74 on its exterior, designed to be connected to any suitable load to supply the electricity generated by the fuel cell assembly 10 to the load.

[0041] With further reference to Fig. 3 The second electronics housing 80 includes a power conversion unit 82. The power conversion unit 82 is designed to convert the electricity generated by the fuel cell assembly 10 for use by a load, if necessary. For example, the power conversion unit 82 is designed to convert the low-voltage direct current generated by the fuel cell assembly 10 into a usable alternating current and essentially acts as a bridge between the fuel cell assembly 10 and the electrical load to ensure stable and efficient power output. Although it is described that the first electronics housing 70 includes the power sensing module 72 and the second electronics housing 80 includes the power conversion unit 82, both the first electronics housing 70 and the second electronics housing 80 can include any other suitable electronic components of the fuel cell assembly 10.

[0042] With reference to Fig. 5. The fuel cell stack subassembly 50 further comprises a compression band 180 designed to hold the individual fuel cells of the fuel cell stack subassembly 50 together. A fastening assembly 182 includes various fastening elements (such as screws and bolts). The compression band 180 can be adapted to accommodate a larger or smaller number of fuel cells contained in the fuel cell stack subassembly 50, depending on the application.
