FUEL CELL STACK AND METHOD FOR OPERATING A FUEL CELL STACK

A fuel cell stack includes multiple stacked individual cells each having an anode and a cathode, a common fuel inlet duct, a common fuel outlet duct, a common oxidizing agent inlet duct, a common oxidizing agent outlet duct, and at least one microwave source configured to selectively generate microwave radiation into the common fuel outlet duct and/or into the common oxidizing agent outlet duct tomanage water contained therein to melt ice and/or expedite evaporation. 燃料电池堆包括每个都具有阳极和阴极的多个堆叠的单电池、公共燃料入口通道、公共燃料出口通道、公共氧化剂入口通道、公共氧化剂出口通道以及至少一个微波源，至少一个微波源配置成选择性地产生微波辐射，微波辐射引导到公共燃料出口通道和/或公共氧化剂出口通道中，以管理其中包含的水来熔化冰和/或促进蒸发。
