Fuel cell is a chemical device that converts the chemical energy of fuel directly into electrical energy. It is also known as electrochemical generator, which is the fourth power generation technology after hydropower, thermal power generation and atomic power generation. Because the fuel cell converts the Gibbs free energy part of the chemical energy of the fuel into electrical energy through electrochemical reaction. It is not limited by the Carnot cycle effect, so the efficiency is high. In addition, the fuel cell uses fuel and oxygen as raw materials. And there is no mechanical transmission component. So the emission of harmful gases is very little and the service life is long. Thus, from the perspective of saving energy and protecting the ecological environment, fuel cells are the most promising power generation technology

Proton exchange membrane fuel cells that directly use methanol as fuel are often called direct methanol fuel cells (DMFC). The membrane electrode is mainly composed of methanol anode, oxygen cathode and proton exchange membrane (PEM). The anode and cathode are respectively composed of stainless steel plate, plastic film, copper current collecting plate, graphite, gas diffusion layer and catalytic layer with porous structure. The gas diffusion layer supports the catalytic layer, collects current and conducts reactants. And is composed of carbon paper or carbon cloth with conductive function. The catalytic layer is the site of electrochemical reaction. And the commonly used anode and cathode electrode catalysts are PtRu/C and Pt/C respectively.
