Description
[ technical field ]

The hydrogen fuel cell system mainly includes: the fuel cell system comprises a galvanic pile unit, an air fuel unit, a hydrogen fuel unit, a thermal management unit, a control unit and a hydrogen storage unit. The fuel cell generates a large amount of waste heat in the hydrogen energy conversion process and needs to be discharged in time. Liquid-cooled fuel cells and air-cooled cells can be classified according to the difference of refrigerants. The hydrogen storage modes of the hydrogen fuel cell include high-pressure hydrogen storage, liquid hydrogen storage and solid hydrogen storage. The solid-state hydrogen storage utilizes special alloy to release heat to absorb and store hydrogen, the hydrogen storage pressure can be as low as 1-5MPa, and the solid-state hydrogen storage has the characteristics of low hydrogenation pressure, high hydrogen storage density, high safety and wide application prospect. The hydrogen fuel required by the operation of the solid hydrogen storage fuel cell is realized by heating the solid hydrogen storage alloy to release gaseous hydrogen.
In order to improve the energy utilization efficiency and the volumetric energy density of a solid hydrogen storage fuel cell system, a technology for releasing hydrogen from waste heat of a solid hydrogen storage absorption system has been reported in related documents. For example, document 1 (fuel cell module with heat exchange and power exchange [ P ]. china: CN2563756) discloses a fuel cell system for a notebook computer, which uses the heat discharged from a host to heat a hydrogen storage unit. Document 2 (Liu Shi Xiang, Wang Cheng and Mao Zong, China: CN101118969, 2008-02-06) and document 3 (Lu Wei Zhong, research on novel air-cooled self-humidifying proton exchange membrane fuel cell technology [ D ]. Harbin engineering university) disclose a coupled hydrogen storage unit, which is characterized in that the hydrogen storage units are arranged between adjacent fuel cells at intervals in a flat plate structure, the surface of a fuel cell polar plate is contacted with the outer wall of the hydrogen storage unit, waste heat generated by the fuel cells is absorbed through a heat transfer medium, and a fan, a water pump and a refrigerant are not used. Document 4 (patent EP0917225a1) discloses an air-cooled fuel cell system, which is characterized in that air for cooling a stack to absorb heat and raise temperature is used to heat a solid hydrogen storage alloy, and hydrogen is released to supply to a hydrogen fuel cell fuel.
However, the following disadvantages exist: the hydrogen storage unit disclosed in document 1 absorbs heat from the host computer and discharges waste heat, and does not use the fuel cell system to discharge waste heat. The fuel cell coupled with the hydrogen storage unit disclosed in documents 2 and 3 has the common characteristic that the hydrogen storage unit comprises a plurality of flat-plate hydrogen storage containers which are arranged between adjacent fuel polar plates at intervals, so that the device has a complex structure and low sealing reliability, the resistance of the fuel cell is increased, and the power generation performance of the fuel cell is reduced. The solid-state hydrogen storage fuel cell waste heat recovery device disclosed in document 4 is only suitable for an air-cooled fuel cell stack, the heating medium for heating the hydrogen storage unit is air for absorbing heat and raising temperature after cooling the cell stack, and the temperature of heat dissipation air is easily affected by the ambient temperature, so that the stable operation of the hydrogen storage unit and the cell stack is not facilitated.
