Fueled by vast investments and aggressive environmental regulations, the search for alternative power sources is intensifying. The fuel cell is a clean and efficient power source which in the future could replace the combustion engine.

Current fuel cell solutions target many application areas, from large output (MW) requirements for residential, commercial and industrial power to mid range (5kW to 10 kW) to low power ranges (less than 100 W) for portable or mobile use.

However, deployment of these fuel cell products is restricted by fuel infrastructure. Hydrogen is the primary fuel for fuel cells, and the challenges in building a widespread network of hydrogen refueling stations is a major barrier for introducing commercial fuel cell systems.
