Abstract
An example fuel cell stack () includes a cathode plate () having oxidant flow passages () and coolant flow passages (), and a porous anode plate () adjacent the coolant flow passages (). The porous anode plate () includes fuel flow passages () and a network of pores () that fluidly connect the fuel flow passages () and the coolant flow passages (). A membrane electrode arrangement () adjacent the fuel flow passages () generates electricity in a fuel cell reaction. A hydrophilic gas diffusion layer () between the membrane electrode arrangement () and the porous anode plate () distributes water from the coolant flow passages () to maintain or establish a wet seal () within the network of pores () that limits fuel transport through the network of pores () from the fuel flow passages () to the coolant flow passages ().
