Description

technical field [0001] The invention relates to a MEMS methanol reforming fuel cell system and belongs to the field of methanol reforming fuel cells. Background technique [0002] As a new type of energy, MEMS micro energy is widely favored by all walks of life due to its high energy density. Among them, the proton exchange membrane fuel cell has become one of the most promising energy systems among various MEMS micro energy systems due to its simple structure, portability, and environmental friendliness. The proton exchange membrane fuel cell uses hydrogen as fuel, reacts with cathode oxygen under the action of the anode catalyst to convert chemical energy into electrical energy, and outputs it through an external circuit. The proton exchange membrane fuel cell has extremely high energy density, and because it directly converts chemical energy into electrical energy without involving the conversion of mechanical energy, that is, it is not limited by the Carnot cycle, and c...
