Fuel cell technology is not 100% dependant upon using hydrogen for fuel,...in fact there are municipal utioities coupled to city sewage plants that burn methane liberated from the solids. <br /> <br />The biggest problem with the idea of using fuel cells for transportation is that in order for the maximum efficiency of the cycle to be exploited, you have to use the heat produced efficiently in addition to the use of the electricity produced... Last I checked, which was 3 years ago, the energy output of most conventional fuel cells was 40% electricity, and 60% heat. <br /> <br />So, PERHAPS a steam fuel cell hybrid might make sense (some day) with the heat by product used to create steam to run turbine generators?
