The basics of fuel cell technology are about 200 years old, and have been improved exponentially over that period. NASA has been using fuel cell technology to power space-bound tech since the 60s.

The first hydrogen fuel cell-powered car was the Chevrolet Electrovan. Originally planned to be a hydrogen-powered Corvair, Chevy soon realized the fuel system was far too large to work in anything smaller than a van. GM built a working example in 1966, but it was far too costly for a production run.

After the Electrovan, hydrogen fuel cell cars languished in obscurity until Toyota took up the torch of emission-free technology. Toyota has been perfecting the fuel cell for years, and is ready to push it as a mainstay of their brand. Toyota is all in on hydrogen, be it hydrogen combustion engines or hydrogen fuel cells. It has multiple initiatives for the fuel source, and here's what you need to know about its fuel cell technology.

In order to give you the most up-to-date and accurate information possible, the data used to compile this article was sourced from Toyota and its press releases.

Hydrogen may seem like a pipe dream, but Toyota truly believes in it and is not slowing down despite its progress in EVs.
