The Canadia Fim and Nasdaq listed, Ballard Power Systems, has just posted a slightly reduced Q2 loss, of $29.5 million.

BPS is the world's leading supplier of fuel cells, fuel cell engines, fuel cell components and electric drive systems to the car industry. Its stock flew high in the late 1990s when fuel cell cars were widely perceived to be just around the corner . . . but they weren't.

6 years later, BPS is still trying to get out of the laboratory and into the market. Still, it has big clients, including Ford and Mercedes Benz who's own investment in fuel cells is tied up with companies like BPS.

In transport though, because of the prohibitive cost, it looks more likely that fuel cells will break only into rich world government funded public transport buses and the deep pockets of the US military.

Fuel cells in regular passenger cars are some way off . . .
