The development of fuel cells over the last century has been heavily influenced by external factors. Initially, fuel cells were seen as an attractive means for the generation of power because the efficiencies of other technologies were very poor. However, as the efficiency of these other technologies rapidly improved, the interest in fuel cells faded. Then, in 1950s fuel cells were rapidly developed for application in space. More recently, significant technical progress in fuel cell technology has made fuel cells appear more viable than ever for a variety of applications. Additionally,...
