Neah Power Systems, Inc. Tel: 425.424.3324 Neah Power Systems is developing a micro fuel cell with a patented technology called Porous Silicon Methanol Fuel Cells. Neah’s technology replaces the proton exchange membrane used in traditional micro fuel cells with a silicon architecture that greatly expands the fuel cell’s catalytic reaction area, thereby significantly increasing its power output and dramatically increasing run time. It also eliminates the “methanol crossover” (i.e. methanol leaking through the membrane) problem inherent in most Direct Methanol Fuel Cells. Leroy Ohlsen conceived the idea for the silicon based micro fuel cell as a chemistry major at the University of Washington. Traditonal Direct Methanol Fuel Cells use a polymer exchange membrane to produce electricity from methanol. "Methanol crossover" occurs when methanol leaks through the membrane, reducing the efficiency and life of the fuel cell. Leroy's idea was to replace the polymer membrane with porous silicon. This eliminated them methanol crossover problem and, because the silicon presented a much larger reaction area, resulted in increased performance and longer run times. After graduation, in 1999, Leroy and his high school friend Mike Fabian founded Neah Power Systems. They submitted a business plan to Seattle's Alliance of Angels in 2000, a network of angel investors, and received series A venture funding in 2001 that raised $2 million from Frazier Technology Ventures (led by Dan Rosen, chairman of the Alliance of Angels) and several other investors. Neah Power Systems began in a house
where Ohlsen, Fabian, and a group of scientists and engineers lived
and worked. They eventually moved into the Washington Technology Center,
a non-profit lab at the University of Washington, where they developed
and patented the technology and named it Porous Silicon Methanol Fuel
Cells. Rosen arranged for Alf Bredlund, former Rayovac scientist, to
perform due diligence on Neah's technology. He concluded that Neah had
a potential breakthrough energy technology with significant market potential.
Under Rosen's guidance, Neah decided to target their micro fuel cell
to the mobile computing market. $3.5 Million in Federal Funding
