Commuter morning, saw a convoy of three Hyundai Tucson FCVs. Also the world's first mass-produced fuel cell vehicle available in the US. The Tucson Fuel Cell is only available as a 3-yr lease, $3K down and $499 a month, the state might still have rebates on it.
The fuel cell system makes its electricity from an electro-chemical reaction between hydrogen and air. Hydrogen in high-pressure tanks pass through a membrane that strips away their electrons, creating the electricity to power the 134-hp AC drive motor. Water vapor comes out of the pipe. The Tucson takes about ten minutes to fill its two 10,000 psi rated hydrogen tanks. It has a claimed 265-mile range but it is still very difficult to live with because of the limited hydrogen filling stations.
Where I LA-LA live, Hyundai is based here and they do have a convenient hydrogen filling station.
