✦ Synopsis

The work described in this paper was oriented towards fuel cells for practical applications, but mainly presents data obtained using half-cells. The economic significance of these data is discussed, together with the technical concept of fuel cell power stations and for transportation applications.

The proposed fuel cell will generate power at much lower costs than conventional power plants, and a zero-emission vehicle with fuel cells will operate at lower fuel cost than a car with an internal combustion engine. The simple falling-film process leads to high power densities (6 kW/l) and low cost. The details given are valid for the use of hydrogen produced from fossil energy sources. Concentrated COI, a byproduct of this technology can be stored in discussed oil and gas fields at a very low cost to avoid global warming. Thus, this 'down-to-earth' hydrogen technology is as free from CO2 emissions as solar-hydrogen technology.
