First up was H-tec, a producer of fuel cell education products since 1997, who announced yesterday that they had sold 10,850 educational units over the course of last year.

The German Centre for Aerospace and Institute for Thermodynamic Technology (DLR) are working with Airbus on developing a fuel cell system to replace aircraft Auxiliary Power Units (APUs). APU's are typically used to power the, so called, hotel loads which include air conditioning, in-flight entertainment, and catering facilities. Replacing engine-powered APUs with fuel cell-powered units would go some way to reducing emissions and improving the efficiency of aircraft.

Proton have also completed one forklift trial, with another planned this year and are developing a 150 kW boat propulsion system for the City of Hamburg.
