FUEL PROCESSING OF BIOGAS FOR SMALL FUEL-CELL POWER-PLANTS

Biogas has a huge potential as fuel for fuel cell power plants. In the present work developments in fuel processing of biogas for a phosphor ic acid fuel cell power plant to be located in rural India are describ ed. Experimental work including steam reforming and shift conversion o f biogas and methane has been carried out in a laboratory development unit. It is confirmed that biogas is not only a useful fuel but also t hat the carbon dioxide in biogas has a positive effect on methane conv ersion. The biogas fuel cell power plant will give a high electrical e fficiency on the small scale of biogas units.
