Fuel cells for powering homes

Fuel cells are similar to batteries, but they differ from them mainly in that they are continually resupplied by the reagents consumed, typically oxygen and hydrogen. One of the applications that fuel cells may have is the supplying of homes with electrical power. When considering applications of this type that call for greater power, a research group has studied the use of one type of material, perovskites, for the design of these cells.http://feeds.sciencedaily.com/~r/sciencedaily/~3/u...
