Phosphoric acid electrolyte in the exhaust gas of a fuel cell (10) is removed in a device comprising a heat exchanger (34) which reduces the temperature of the gas to below the acid condensation point, followed by an accumulator (36) including a plurality of vertically oriented, spaced apart, open porosity plates (52) which pick up the acid as the gas stream flows between the plates. The plate spacing, pore size and porosity are selected such that virtually all the acid is drawn into the plates and passes down through the pores of the plates and drips off the plates under gravitational forces, whereupon it is removed from the device via a drain (62) and can be recirculated to the fuel cell if desired. <IMAGE> |
