In such a world, fuel cells would replace the internal combustion engines in cars and the steam turbines in power stations as the means of turning chemical energy into useful power. Rather than burning carbon-based fuels and therefore releasing carbon dioxide, fuel cells convert the chemical energy of hydrogen directly into electricity, producing only water as a by-product. Furthermore, since a fuel cell is not subject to the same thermodynamic constraints as a heat engine it can be made much more efficient than an internal combustion engine.Read More
