Description

[Technical Field]

[0001] This utility model belongs to the field of hydrogen energy systems, specifically an integrated hydrogen energy air-cooled fuel cell stack system. [Background Technology]

[0002] Currently, the market is dominated by distributed systems, with the control system and hydrogen energy conversion unit being separately and independently controlled. This results in complex control, as multiple control systems need to be connected through hydrogen energy pipelines, signal lines, etc. This poses various risks such as line damage, pulling, and hydrogen energy pipeline breakage. At the same time, the appearance is also very messy, with the lines and pipelines being very chaotic, causing a lot of inconvenience to the user.

[0003] Existing fuel cell stack systems are mainly decentralized and independent, such as the control system being a separate control system and the hydrogen system being a separate hydrogen system. This is not integrated into a whole system, and each system needs to be installed independently and connected separately for use. This not only brings heavy workload to the user, but also involves many uncontrollable safety risks. [Utility Model Content]

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing an integrated hydrogen energy air-cooled fuel cell stack system that can output stable voltage and current to external systems and can perform complete charging and discharging, thus avoiding the heavy workload and uncontrollable safety risks associated with traditional fuel cell stack systems.

[0028] This utility model belongs to the field of hydrogen energy systems and relates to a low-power air-cooled fuel cell stack system, also known as an air-cooled stack.

It allows for complete removal and placement, as well as independent removal and placement of hydrogen cylinders. Simultaneously, the system utilizes the hot air from the air-cooled stack to self-melt any frost or other buildup that may occur during hydrogen cylinder use, thus forming a complete air-cooled stack system.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0030] As attached Figure 1 The diagram shows the overall external structure of the unit. Hydrogen cylinder 1 is used for storing hydrogen. A gas pipe connects to this cylinder, facilitating the supply of hydrogen to the electrodes 20 within the hydrogen-to-electricity conversion unit. Handle 2 connects to the top plate 8, primarily for easy access to the entire air-cooled reactor system. Low hydrogen indicator 3 provides an alarm when the hydrogen in cylinder 1 is nearly depleted or reaches a certain low pressure. Quick-connect communication connector 4 is the communication interface between this air-cooled system and user devices such as shared bicycles, shared electric vehicles, and drones, facilitating power transmission and system signal exchange. Hook 5 is mainly used for installation with shared bicycles, shared electric vehicles, and drones, providing a secure connection between the air-cooled reactor and the user device. Front cover 6 encloses the front part of the air-cooled reactor, allowing for quick disassembly for easy installation and maintenance of the front section, while also protecting the internal structure from exposure or damage. Rear cover 7: This cover has the same function as the front cover 6, mainly sealing the rear part of the air-cooled reactor to facilitate the installation and maintenance of the internal structure, while also providing protection to prevent the internal structure from being exposed or damaged. Top plate 8: This plate is installed on the top, and handle 2, hydrogen shortage indicator 3, and communication quick-connect connector 4 are installed on this plate, while also sealing the top of the entire air-cooled reactor.

[0031] As attached Figure 2 The diagram shows the rack structure. Fan 9 is used for air intake, drawing air through the openings in the front cover 6 to provide sufficient air for the hydrogen reaction, maximizing the utilization of hydrogen and converting it into electrical energy. Simultaneously, the heat generated during the energy conversion process is carried away by this fan, providing cooling. The air then passes through the fixed cover 10 and is directly blown onto the hydrogen cylinder 1, heating and melting any frost on it. This provides both intake and blowing functions. The fixed cover 10 holds the hydrogen cylinder in place and also houses the inlet solenoid valve 22 and outlet solenoid valve 23. The sealing plate 11 acts as a seal, separating the reactor from the reactor control plate 12, allowing air to pass only through the openings in the front cover 6. The reactor control plate 12 controls the entire air-cooled reactor, providing a stable output of the electrical energy converted from hydrogen, including voltage and current. The fixed cavity 13 has a U-shaped structure and is mainly used to install the hydrogen energy conversion to electricity unit, the stack control board 12, and the fan 9. It also serves as a sealed space to isolate it from other components.

[0032] As attached Figure 3The diagram illustrates the structure of a hydrogen-to-electricity reactor. The upper end plate 14 primarily functions as an end-face clamping plate. A screw 16 passes through this end plate and connects to the lower end plate 17, thus clamping the membrane electrode assembly (MEA21) and electrode plates 20, facilitating the electrochemical reaction between hydrogen and air. The sealing ring 15 seals the process holes on the upper and lower end plates 14 and 17, preventing air from entering the reactor from other locations. This ensures air can only enter through the holes on the front cover 6, thus guaranteeing the overall performance of the air-cooled reactor. Six screws 16 connect the upper and lower end plates 14 and 17, three at the front and three at the back. The lower end plate 17 serves the same function as the upper end plate 14; the screw 16 passes through this short plate and connects to the upper end plate 14, clamping the membrane electrode assembly (MEA21) and electrode plates 20. Hydrogen enters through connector 18, which connects to hydrogen cylinder 1 via a gas pipeline, thus delivering the hydrogen from cylinder 1 to the hydrogen-to-electricity conversion system. Hydrogen output connector 19 is used to discharge residual gas from the hydrogen-to-electricity conversion system into the atmosphere. Electrode 20, made of graphite, primarily outputs the electrical energy generated by the membrane electrode assembly (MEA21). Due to its graphite material, it provides excellent conductivity. A wind-cooled reactor may have a few or many electrode plates 20, depending on the total output power of the system; higher power requires more plates, and lower power requires fewer. Electrode MEA21 generates electricity through an electrochemical reaction between hydrogen and air. Similar to electrode 20, a wind-cooled reactor may have a few or many electrode plates 20, depending on the total output power of the system; higher power requires more plates, and lower power requires fewer.

[0033] As attached Figure 4 The diagram shows the structure of the control section. The intake solenoid valve 22 connects to the hydrogen cylinder 1 at one end and to the hydrogen inlet connector 18 at the other, controlling the flow of hydrogen. The exhaust solenoid valve 23 connects to the hydrogen outlet connector 19 at one end and to the atmosphere at the other, controlling the emission of hydrogen from the reactor. The bottom mounting plate 24 is mounted on the lower end plate 17 at one end and on the mounting cavity 13 at the other, securing the reactor in place.

[0034] As attached Figure 5 The diagram shows the structure of electrode 20. Air flows through the air channel 25, which enters from the front cover 6 and flows through the reactor, providing sufficient air to the reactor and carrying away heat from electrode 20. Hydrogen flows through the hydrogen inlet 18, where hydrogen enters and then contacts the membrane electrode 21 (MEA), reacting with the air to generate the required electrical energy, which is then output through electrode 20.

[0035] The working principle of this utility model is as follows: The entire air-cooled stack is placed inside a shared bicycle, shared electric vehicle, or drone → the communication quick-connect connector 4 establishes a signal interaction connection with the shared bicycle, shared electric vehicle, or drone → the start-up control controls the start-up of the air-cooled stack → hydrogen gas in the hydrogen cylinder 1 enters the flow channel of the electrode plate 20 through the inlet solenoid valve 22 → hydrogen gas and air come into contact with the membrane electrode MEA 21 to undergo an electrochemical reaction, thereby generating electrical energy → 6. The electrical energy is output through the electrode plate 20 to drive the user end to operate, thereby controlling the operation of terminals such as shared bicycles, shared electric vehicles, and drones.
