Thermal Analysis of Methanol Reforming Proton Exchange Membrane Fuel Cell System

KEYWORD:Methanol reforming hydrogen production, Proton exchange membrane Fuel Cell, Waste heat analysis, system optimization. ABSTRACT:Relatively mature methanol reforming PEMFC products have been produced domes- tically, and power generation efficiency of the whole system can reach 30%, but most of the waste heat is not used. Based on an experiment table of methanol reforming PEMFC system, a large mount of data about the internal temperature, pressure, electric current, voltage of the whole system running under different output power is collected, and the actual waste heat generated by the system at different output power is calculated. Then the theoretical calculation of waste heat is compared with the actual value of waste heat of the system. The direction of waste heat utilization and opti- mization of the whole system is proposed.
