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 to manage water contained therein to melt ice and/or expedite evaporation.
