If you compare engines and fuel cells, there is a distinct difference in cost and lifespan. Toyota builds their engines for a lifespan of 250,000mi, and I’ve owned and worked on […]

The researchers try to prove with every chance they got that fuel cells which can provide the required energy for a certain application and that they are very reliable. ACAL Energy (Cheshire, UK) has recently developed a liquid cathode […]
