The amount of money being spent to research and develop vehicles powered by alternative fuels is staggering. Much of the research time and money is being spent on electric vehicles and battery technology.
However, other alternative fuel sources are being researched as well like fuel cells. GM has been testing hydrogen fuel cells in the Chevy Equinox for several years now. One of the things I have always wondered was exactly how a fuel cell was built and how far the tech as come since GM first started working on it about three years ago.
GM has a new video that goes over the construction process of a fuel cell prototype and shows how far the tech has come. The first fuel cells form three years ago were large devices. Today's fuel cells are significantly smaller than the older versions, yet produce more power. Hit the video below to see for yourself.
