It also develops its own PEM (proton exchange membrane) fuel cell generators and has a growing business in China, where it will power the buses for the 2008 Beijing Olympics.

But until recently they have suffered from a low power-to-weight ratio, unlike the other sort of room-temperature fuel cell, the temperamental and costly proton-exchange-membrane device, which several firms hope soon to use in motor cars.
