ABSTRACT
It has taken since 1839, when Sir William Grove invented the technology, for the fuel cell to be recognized as the likely principal power source of the future. It is the fuel cell that will be the bridge between the hydrocarbon economy and hydrogen-based society. David Hart who is head of fuel cells and hydrogen research at Imperial College has no doubt about the possibilities for fuel cells:
If fuel cells fulfil their potential, there’s no reason why they shouldn’t replace almost every battery and combustion engine in the world.1
