Northwest Power Systems (NPS) of the USA has announced that it has demonstrated a new fuel processor technology that is able to convert diesel into high-purity hydrogen. The device produces hydrogen that is pure enough to use in a proton exchange membrane fuel cell system.

NPS developed the diesel fuel processor under a 50 per cent cost sharing system in association with Sandia National Laboratories, a prime contractor to the US DoE. The NPS design incorporates a purification stage that produces hydrogen of greater than 99.8 per cent purity, containing less than 1 ppm CO and 1 ppm CO2. No further purification is required before passing the hydrogen into any conventional PEM fuel cell stack.
