Abstract

The invention discloses a fuel cell system comprising a hydrogen supply module, a fuel cell module and a control module. The fuel cell module is used for receiving hydrogen supplied by the hydrogen supply module. The fuel cell module comprises a fuel cell unit and a hydrogen storage unit which are communicated with each other. The control module is electrically connected with the fuel cell module so as to control the hydrogen storage unit to store or release hydrogen.

Description

【Technical field】 [0001] The invention relates to a fuel cell system. 【Background technique】 [0002] A fuel cell is basically a power generating device that converts chemical energy into electrical energy using the reverse reaction of electrolysis of water. Taking a proton exchange membrane fuel cell (PEMFC) as an example, the proton exchange membrane fuel cell mainly includes a membrane electrode assembly (MEA) and a hydrogen supply module, wherein the hydrogen supply module will The hydrogen gas (H 2 ) is guided to the membrane electrode group, so that the hydrogen gas undergoes an electrochemical reaction therein. [0003] The hydrogen generated by the hydrogen supply module can be converted into solid sodium borohydride (NaBH 4 ) reacts with water. But this chemical reaction is a chemical reaction, that is, hydrogen will be continuously generated until the chemical reaction between solid sodium borohydride and water is completed. Therefore, when the membrane electr...
