Farad - Model DMFC -Fuel Cell

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.
