Hydrogen on Wheelsby Jim

Today I got to drive a hydrogen fuel-cell powered car. Justin and I went to downtown Livermore to the event and got to test-drive a hydrogen Nissan. We only got to drive it half-way around the block, but it was still really cool. All of the hydrogen cars are actually hybrids; they are part fuel-cell, part electric. When the engine needs a little more oomph, there is a lithium ion battery that kicks in. Also, you get regenerative braking that charges the battery. Very cool.

For the geeks out there, it was a PEM hydrogen fuel cell. (That’s Proton Exchange Membrane, just in case you didn’t know that.) Check out the Wikipedia article for more cool stuff.

    That’s really cool. I’m glad you didn’t explode. 🙂 (I worked for mechanical engineers who expressed significant amounts of concern about exploding cars.)
