Phosphoric acid cells
are around 40 percent efficient and operate at about 200 [degrees] C.
Unlike polymer electrolyte membrane fuel cells under investigation for automotive power plants, the amount of platinum in the Onsi phosphoric acid cells
represents a mere sliver of their cost--$30 to $40 per kilowatt, according to Trocciola.
PEM fuel cells operate at around 80 C, phosphoric acid cells
at 200 C, molten carbonate at 600 C, and solid oxide at 1000 C.
While somewhat newer battery technologies like Lithium and Nickel Metal Hydride offer alternatives to traditional lead acid cells
, they have their own set of issues including higher costs.
