This paper discribe the characteristics of start-up of polymer electoryde fuel cell at the low temperature, -20deg.C. As the result,the power is generated at the low current density and dropped by the freezing of the produced water at the cathode side. The fuel cell maintained a uniform cell voltage without humidification at low temperature and low current density because of a balance of water generated at the cathode with one carried away by the exhaust gas.By the experiment, it is difficult to start up fuel cell at the low temperature, -20deg.C. However, cold-start of fuell cell can be possible by incrasing temperature of supplyed gas.
