Notes to Editors


Proton Power Systems plc, through its wholly owned subsidiary Proton Motor Fuel
Cell GmbH, has developed and produced a fuel cell module running on hydrogen and
integrated with an energy storage system to create a hybrid electric-fuel cell
system. The system harnesses the excess power generated by the fuel cell during
low power demand and the recovered brake energy (such as stop-start operations)
and uses the stored energy in peak demand times.The system thus boasts lower
fuel consumption and more consistent levels of power delivery than conventional
combustion engine or fuel cell-only systems, in addition to producing zero
harmful emissions.



Proton Power's market focus lies in industrial applications where 'back-to-base'
refuelling occurs at the end of each shift or work period, such as in the
materials handling and mass transportation sectors. The Company's proton
exchange membrane (PEM) fuel cells can replace batteries, and the systems are
already deployed in city buses and forklift trucks. The company has also
identified secondary market opportunities in stationary backup applications such
as UPS and APUs.



Proton Power was admitted to trading on AIM on 31 October 2006. It is based in
Puchheim, near Munich, Germany.
