While most of the world follows the Lithium-Ion battery based electric car design there are some others that still believe in the Hydrogen Fuel Cell. GM have recently improved their fuel cell design further by halving the size of the fuel cell and reducing the cost of production.
The size of GM’s fuel cell is now comparable with an average four cylinder engine whilst still maintaining the same 93 kW (125 BHP) power output as previous designs. The test-bed Chevy Equinox fuel cell vehicle has a maximum range of 150 miles and a top speed of 100mph, if they had used a smaller model then I expect these figures would have been better.
Production costs have been cut by halving the amount of platinum used in the fuel cell, with further reductions expected in the future. With production planned for 2012 the only concern is the costly drive train which will need refining in order to make the cost of the car viable.
Whilst there is still a carbon cost associated with producing hydrogen it is still by far the cleanest of current alternative fuel designs. My main concern is that a hugely expensive infrastructure will be rolled out to accommodate the recharging of popularised Lithium-Ion cars. Nobody is going to want to repeat the process for Hydrogen refilling stations.
