Abstract
An integrated condenser/separator (10) is provided for condensing and separating a condensate (11) from a cathode exhaust gas flow (12) in a fuel cell system (14). The condenser/separator includes a housing (16) and one or more baffle plates (18, 20) positioned in the housing (16) to divide the interior of the housing (16) into two or more gas flow chambers (24, 26, 28) each containing a stack (32, 34, 36) of heat exchange units (30). A condensate drain (106, 108) is provided in each of the gas flow chambers (24, 26) to drain condensate therefrom. The condenser/separator (10) can be configured into any reasonable and independent number of coolant and gas side passes as maybe required to meet the thermodynamic and pressure drop requirements of each particular application.
