All fuel cells currently being developed for near term use in electric vehicles require hydrogen as a fuel. The recent progress of fuel cell development towards highly efficient and clean energy conversion allows increasing applications in the wide field of on-board electricity generation and alternative drive systems. Since the first practical uses of fuel cells were developed, it has become clear that they could find use in many products over a wide power range of milliwatts to tens of megawatts. Throughout the 1990s, and later, there has been significant work carried out on adapting the various different fuel cell technologies for use in targeted consumer and industrial applications. This paper discusses these developments and gives the types of fuel cells in details, applications, benefits, futures large and small-scale stationary power generation.
