Abstract
Structures and methods are disclosed for removing water, and particularly for preventing ice blockages, in solid polymer electrolyte fuel cells comprising reactant vias that fluidly connect a reactant transition region to a reactant port. Water can be removed from the reactant via by making its surface superhydrophobic while incorporating at least one additional via with a hydrophilic surface in parallel therewith.
