Reformed methanol fuel cell

Reformed methanol fuel cell (RMFC) or indirect methanol fuel cell (IMFC) systems are a subcategory of proton-exchange fuel cells where, the fuel, methanol (CH3OH), is reformed, before being fed into the fuel cell. RMFC systems offer advantages over direct methanol fuel cell (DMFC) systems including higher efficiency, smaller cell stacks, less requirement on methanol purity, no water management, better operation at low temperatures, and storage at sub-zero temperatures because methanol is a liquid from −97.0 to 64.7 °C (−142.6 to 148.5 °F) and as there is no liquid methanol-water mixture in the cells which can destroy the membrane of DMFC in case of frost.
