The present disclosure provides for fuel cell systems, assemblies and methods. More particularly, the present disclosure provides for emergency power fuel cell systems, assemblies and methods (e.g., for aircraft or the like), with the fuel cells having indirect evaporative cooling. The present disclosure provides that a liquid-air heat exchanger that exchanges heat carried by hot coolant (18) from a fuel cell with ambient air can be replaced by a heat exchanger that transfers heat from the fuel cell to grey water (130) (e.g., grey water that is stored on an airplane or the like) that is allowed to evaporate. As such, this substantially eliminates the coolant fans, and can result in a smaller and/or lighter heat exchanger.
