Abstract:
Since the industrialisation of fuel cell technology during the 1970s and 80s, molecu3
3 lar hydrogen (H2) has been considered as a clean alternative for fossil fuel based energy
34 carriers. The selective oxidation of H2 by oxygen only produces water, contrary to the
35 combustion of fossil fuels with air that produces carbon dioxide, carbon monoxide, ni3
6 trogen oxides, soot, and many other volatile organic compounds. As H2 is not readily
37 available in large quantities, practical applications of fuel cell technology rely on conver3
8 sion from other energy carriers (e.g. bio fuels or fossil fuels) or generation of H2 from
39 direct energy sources (e.g. solar energy). The low overall well-to-wheel eciency of the
40 entire energy production chain and the accompanying costs, have so far limited the use of
41 H2 to a relatively small number of applications. Nevertheless, the potential for improving
42 urban air quality and reducing the human impact on climate remains appealing.
