Abstract
A fuel cell may include a first fuel cell bipolar plate defining an air layer, a second fuel cell bipolar plate defining a hydrogen layer, and a coolant layer defined by the air layer and the hydrogen layer. The coolant layer includes a plurality of coolant microchannels that facilitate flow of a coolant. A permeable support layer is arranged between the air layer and the hydrogen layer to define a gap therebetween to prevent flow blockage of the coolant microchannels while facilitating coolant flow therethrough.
