摘要： A catalyzed burner is operative to combust an anode exhaust stream from a polymer electrolyte membrane (PEM) fuel cell power plant. The catalysts coated onto the burner can be platinum, rhodium, palladium, 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. The burner is able to combust hydrogen in the anode exhaust stream. The catalyzed burner has a high surface area wherein about 70-90% of the volume of the burner is preferably open pores, 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. (927° C.). The burner can combust anode exhaust during normal operation of the fuel cell assembly. The burner is not adversely affected by gasoline, gasoline combustion products, 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.
