The invention is a fuel cell with an electrolyte dry-out barrier to restrict loss of water from the electrolyte. The fuel cell includes: an anode catalyst and a cathode catalyst secured to opposed sides of an electrolyte; an anode flow field disposed adjacent the anode catalyst for directing the red
The invention is a fuel cell with an electrolyte dry-out barrier to restrict loss of water from the electrolyte. The fuel cell includes: an anode catalyst and a cathode catalyst secured to opposed sides of an electrolyte; an anode flow field disposed adjacent the anode catalyst for directing the reducing fluid to pass adjacent the anode catalyst, and a cathode flow field disposed adjacent the cathode catalyst for directing the process oxidant stream to pass adjacent the cathode catalyst; and, an anode electrolyte dry-out barrier secured between the electrolyte and the anode flow field for restricting transfer of water from the electrolyte into the anode flow field. The anode electrolyte dry-out barrier extends from adjacent an entire reducing fluid inlet and along an entire reducing fluid flow path a distance that is adequate for the reducing fluid stream flowing through the anode flow field to become saturated with water. The fuel cell may also include a cathode electrolyte dry-out barrier secured between the electrolyte and the cathode flow field. The anode and/or cathode electrolyte dry-out barriers may consist of polymeric sealants coating or impregnating barrier regions of porous layers between the electrolyte and the anode and/or cathode flow fields.
