[0003] There are many types of emergency power sources, such as diesel generators, lithium batteries or lead-acid batteries, etc. Diesel generators are noisy and produce harmful exhaust gas, which is not friendly to residences or communities; and lithium batteries or lead-acid batteries will discharge naturally if they are not used for a long time, resulting in insufficient or no battery, which is not conducive to use in shelters or field first aid stations.

[0004] At present, some solid-state hydrogen storage systems are also used for emergency power supply, but most of them do not take into account the problems caused by actual application scenarios. In densely populated areas such as towns or rural areas, hydrogen fuel cells are not as convenient to use as emergency power supply as lithium batteries or lead-acid batteries; in shelters and field emergency stations, it is necessary to consider that the equipment may not be used for more than a few years, and when it is needed urgently, the emergency power supply fails because the equipment has no power to start the fuel cell system, which greatly reduces the last lifeline of the place.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.

[0030] Example 1

[0031] like Figure 1-Figure 5As shown, a solid-state hydrogen storage emergency power supply includes a power supply housing 1, a solid-state hydrogen storage system 2, a fuel cell system 3, an energy storage battery 4, a DC-AC inverter 5 and a hand-cranked generator 6. A power supply interface 7 is provided on the power supply housing 1, and the power supply interface 7 is used to supply power to external equipment; the solid-state hydrogen storage system 2 is connected to the fuel cell system 3 through a hydrogen pipeline, and is used to supply hydrogen to the fuel cell system 3; the power output end of the fuel cell system 3 is connected to the power input end of the energy storage battery 4, and the energy storage battery 4, the DC-AC inverter 5 and the power interface 7 are circuit-connected in sequence, and the power output end of the energy storage battery 4 and the power output end of the hand-cranked generator 6 are both connected to the power input end of the fuel cell system 3, and are used to provide the fuel cell system 3 with the power required for starting.

[0032] A charging port 11 is provided on the power supply housing 1, and the charging port 11 is connected to the energy storage battery 4. When external electricity is abundant, electric energy can be transmitted to the energy storage battery 4 through the charging port 11. The hand-cranked generator 6 is connected to the fuel cell system 3. A blower 8 is provided on the fuel cell system 3, and the blower 8 transmits air to the fuel cell system 3 through an air pipeline.

[0033] The solid-state hydrogen storage system 2 stores hydrogen at room temperature and low pressure for a long time. When it is needed, the solenoid valve on the solid-state hydrogen storage system 2 can be opened, and hydrogen is transported to the fuel cell system 3 through the solid-state hydrogen storage system 2. The hydrogen is burned inside the fuel cell system 3 to generate electricity. As the fuel cell system 3 is started, the amount of hydrogen consumed is increasing. By fitting the solid-state hydrogen storage system 2 under the fuel cell system 3, the waste heat of the fuel cell system 3 accelerates the release of hydrogen from the solid-state hydrogen storage system for use by the fuel cell system 3. The electricity generated by the fuel cell system 3 can be transmitted to external devices through the energy storage battery 4 and can be supplied to electrical devices through the power interface 7. On the other hand, it can be stored in the energy storage battery 4 to ensure that the fuel cell system 3 is always operating in a high-efficiency area after startup, thereby improving the utilization rate of hydrogen, thereby increasing the power generation per unit of hydrogen, and further improving the endurance of the emergency battery.

[0034] In densely-connected power grids such as towns or rural areas, it is only necessary to charge the energy storage battery 4 through the charging port 11, and discharge it to the outside through the power interface 7 after power failure. Its use is as simple as that of lithium batteries or lead-acid batteries. The energy storage battery 4 can be quickly charged through the charging port 11. When the emergency battery has been stored for more than 3 years and the energy storage battery 4 is depleted and cannot start the fuel cell system 3, at this moment, it is only necessary to operate the hand-cranked generator 6 to supply the power required for starting the fuel cell system 3, so that the fuel cell system 3 can start and generate electricity.

[0035] In the present application, the blower 8 is used to replace the traditional air compressor. On the one hand, it saves the cost of consumables. On the other hand, the air compressor needs coolant for cooling. After replacing it with the blower 8, the pipeline setting in the battery is reduced, the integration is increased, and the pipeline setting is simpler.

[0036] By providing the energy storage battery 4 and the hand-cranked generator 6, not only the endurance is improved, but also the efficient power generation of the fuel cell is improved. In addition, the emergency battery which has not been used for a long time can be started with a simple operation, thus providing a strong guarantee for the power supply of the field first aid station or the avoidance place. The fuel cell product is pure water, which can be supplied when needed.

[0037] Example 2

[0038] The difference between this embodiment and embodiment 1 is that a PTC heater 9 is provided on the fuel cell system 3, and the PTC heater 9 is used to heat the coolant in the fuel cell system 3, so as to heat the coolant of the fuel cell system 3 when the temperature is lower than the set value, so that the fuel cell system 3 can be started smoothly.

[0039] The fuel cell system 3 is connected to the energy storage battery 4 via a DCDC converter 10 . The DCDC converter is air-cooled and does not require a coolant to cool the inside of the DCDC converter 10 .

[0040] The fuel cell system 3 is provided with an air filter 31, which is connected to the air inlet of the blower 8. The air filter 31 is arranged at the upper edge of the inner cavity of the power supply housing 1 to facilitate later maintenance. A large space is reserved around the air filter 31 to ensure that sufficient air flows through the air filter 31.

[0041] The inner cavity of the power supply housing 1 is divided into an upper functional area and a lower functional area 19. The solid-state hydrogen storage system 2, the fuel cell system 3 and the energy storage battery 4 are arranged in the upper functional area, the DC-AC inverter 5 and the hand-cranked generator 6 are arranged in the lower functional area 19. The hand crank 61 of the hand-cranked generator 6 extends out of the power supply housing 1 to facilitate the operation of the hand-cranked generator 6. The present invention has a compact structure and a high degree of integration.

[0042] The fuel cell system 3 is provided with a controller 31, and the controller 31 regulates the flow of hydrogen and air respectively through the solenoid valves provided on the hydrogen pipeline and the air pipeline. The power interface 7 includes a two-phase socket and a three-phase socket, which is convenient for the output of electric energy. The power housing 1 is provided with a fuel cell drain port 12, a fuel cell exhaust port 18 and a solid-state hydrogen storage system 2 hydrogenation port, which are convenient for the discharge of water and the hydrogenation of the solid-state hydrogen storage system 2, and also includes a solid-state hydrogen storage cooling water outlet 16 and a solid-state hydrogen storage cooling water inlet 17. When the solid-state hydrogen storage system 2 is hydrogenated, it is necessary to connect the solid-state hydrogen storage cooling water outlet 16 and the solid-state hydrogen storage cooling water inlet 17, the purpose of which is to cool the solid-state hydrogen storage system during the hydrogenation process.

[0043] A mobile base 14 is provided below the power supply housing 1, and casters 15 are provided on the mobile base 14 to facilitate the movement of the battery and to quickly move the emergency power supply to a destination.

[0044] In the present invention, the throttle valve (set between the stack outlet of the fuel cell system and the tail water tank) and the bypass valve (set between the stack outlet of the fuel cell system and the humidifier) ​​in the fuel cell system 3 can also be replaced by the three-way air valve 32. The three-way air valve 32 is connected to the stack outlet of the fuel cell system 3, and one of the other two ends is directly connected to the tail water tank of the fuel cell system 3, and the other is connected to the tail water tank after the humidifier. Its functionality remains unchanged, the number of parts and brackets is reduced, and the integration of the fuel cell system 3 is improved.

[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0046] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
