摘要：

An essential problem connected with the operation of regenerative fuel cell systems in space is the rejection of waste heat, produced mainly during discharging the regenerative fuel cell. The intention of this investigation was to gain a better understanding of the heat generation and heat rejection mechanism in alkaline fuel cells by performing detailed thermal modelling of a single cell stack. In particular, spatial temperature profiles within the fuel cell stack and the start-up behavior of the cells were predicted. Furthermore a model simulation of an emergency situation due to a partial failure of the coolant circuit was performed and theoretically temperature versus time curves were given for restarting the cooling.
