A burner assembly includes a catalyzed burner for combusting an anode exhaust stream from a polymer electrolyte membrane (PEM) fuel cell power plant. The catalysts coated onto the burner can be platinum, rhodium, or mixtures thereof. The burner includes open cells which are formed by a lattice, which cells communicate with each other throughout the entire catalyzed burner. Heat produced by combustion of hydrogen in the anode exhaust stream is used to produce steam for use in a steam reformer in the PEM fuel cell assembly. The catalyzed burner has a high surface area wherein about 70-90% of the volume of the burner is preferably open cells, and the burner has a low pressure drop of about two to three inches water from the anode exhaust stream inlet to the anode exhaust stream outlet . The burner assembly operates at essentially ambient pressure and at a temperature of up to about 1,700 F. (646 C.). The burner assembly can combust anode exhaust during normal operation of the fuel cell assembly. The burner assembly also includes an adjunct burner which can combust gasoline or anode bypass gas (the latter of which is a reformed fuel gas which is tapped off of the fuel cell stack fuel inlet line) during startup of the fuel cell power plant. Once start up of the fuel cell power plant is achieved, the burner assembly will need only combustion of the anode exhaust by the catalytic burner to produce steam for the reformer.

Fuel from a source () passes through a hydrogen desulfurizer () and a proportioning mixing valve () to a CPO (), the temperature of the output of the CPO being monitored () to provide a signal () which a controller () utilizes to adjust the valve (). The output of the CPO may be passed through a water gas shift reactor () and a preferential CO oxidizer () to provide fuel to a fuel cell system (). The air provided to the valve () may be humidified, such as by an enthalpy recovery device () receiving the oxidant outflow () from the fuel cell system.

Cathode exhaust of an evaporatively cooled fuel cell stack () is condensed in a heat exchanger () having extended fins () or tubes () to prevent pooling of condensate, and/or having the entire exit surface of the condenser rendered hydrophilic with wicking () to conduct water away. The cathode exhaust flow paths may be vertical or horizontal, they may be partly or totally rendered hydrophilic, and if so, in liquid communication with hydrophilic end surfaces of the condenser, and the condensers () may be tilted away from a normal orientation with respect to earth's gravity.
