Problems solved by technology

In the public literature that can be seen so far, the thermal management of the fuel cell and the hydrogen storage unit are considered separately, which is not conducive to reducing the internal power consumption of the fuel cell system, improving efficiency, and is not conducive to improving the performance and performance of the fuel cell. life
Moreover, the hydrogen storage unit and the fuel cell of such a system are separated, and the energy density of the system is not high

Abstract

The present invention discloses a fuel cell of a coupling hydrogen storage unit. The fuel cell monomer comprises a cathode flow field board, an anode flow field board, a membrane electrode and a hydrogen storing unit. The fuel cell of the coupling hydrogen storage unit is formed by the superposition and coupling of the structure, utilizing the property that the hydrogen storing unit release hydrogen to absorb heat and the fuel cell reacts to disperse heat, the coupling of the heat content management of the fuel cell and the hydrogen storing unit are realized. The present invention also enables the hydrogen and air flow passage to be processed and enables the structure of the fuel cell monomer to become much simpler. While solving the problem of heat management of the hydrogen storing unit and the fuel cell, the present invention also can reduce the volume and power consumption of the system of the fuel cell as well as improve the energy density. The fuel cell disclosed in the present invention can be applied in various fields such as power supplies of electronic devices, diverse continuous power systems and the engine systems of motorcars, etc.

Description

technical field [0001] The invention belongs to the field of fuel cells, in particular to solid polymer electrolyte fuel cell technology using hydrogen as fuel. Background technique [0002] A fuel cell is a continuous power generation device that converts chemical energy in externally supplied fuel and oxidant into electrical energy. Because of its high power density and energy density, clean and efficient, and wide power range, fuel cells have broad application prospects in various fields such as micro power sources, mobile power sources, vehicle engines, and stationary power stations, so they have received extensive attention from countries all over the world. The United States, Japan, Canada, and European countries are actively developing fuel cell technology. At present, almost all major automakers in the world are developing fuel cell electric vehicles. [0003] The current fuel cell technology is mainly divided into several types according to different electrolytes, ...
