Abstract
A fuel cellhas a liquid electrolyte, a cathode electrode, and an anode electrode. The fuel cell includes an electrolyte condensation zoneextending from an edgeof a first catalyst layeron the cathode electrode to an outer edgeof an edge sealsand. An anode electrode has an anode catalyst layerwith an end substantially coinciding with an inner edgeof the edge seals. The acid condensation zone is located near the reactant exit, so that electrolyte that has evaporated into the reactant stream can condense out before leaving the fuel cell for re-absorption back into the fuel cell.
