Daihatsu makes platinum-free fuel cell

Japans' Daihatsu Motor said today it developed a technology to make fuel cells without platinum. The precious metal is used in the electrolyte process of existing hydrogen fuel cells.

Daihatsu, the minivehicle unit of Toyota Motor (NYSE: TM), said that by using alkaline instead of acid exchange membranes, its fuel cell can work with less costly metals, such as cobalt or nickel.

Working with Japan's National Institute of Advanced Industrial Science and Technology, Daihatsu said its new technology fixes hydrazine hydrate inside the fuel tank to ensure its safe use as a fuel, resulting in zero carbon dioxide emissions.

Daihatsu said it uses about 100 grams of platinum per vehicle for its hydrogen based fuel cell vehicles currently under development.

Fuel cells aren't a very popular choice for carmakers, but Mercedes-Benz earlier this week touted plans to come out with a fuel cell car (see Fuel cell car coming from Mercedes).

The German luxury automaker said it will come out with a small-scale series production of the B-Class F-Cell vehicle in early 2010.

Daihatsu plans further work on the technology, saying there are still some hurdles to get over before it can be ready for commercial production.

The company said the process needs improvements in the polymer for fixing the fuel, an enhancement of both the performance and durability of the fuel cell, and an establishment of the necessary infrastructure.

The minivehicle maker said it hopes to establish partnerships with other companies and proceed with further research and development.
