Neah Power's Fuel Cell Achieves Excess of 500 Hours of Continuous Operation

BOTHELL, Wash., Oct. 22, 2009 (GLOBE NEWSWIRE) -- Neah Power Systems, Inc.
(OTCBB:NPWZ), www.neahpower.com, the Company developing fuel cell-based
renewable energy solutions, revealed today that its fuel cell has been in
continuous operation for more than 500 hours without any mechanical or
electrical failure or significant degradation in performance. Additionally, Neah
has completed other extensive materials compatibility testing to successfully
qualify cell components for long-term use. All materials have surpassed in
excess of six months of exposure, with some materials in excess of two years of
demonstrated compatibility.

"This represents a huge milestone for our disruptive fuel cell technology in our
view. Our unique, IP protected, silicon based fuel cell technology has
progressed from conception, to proof of concept, to prototype in a short period
of time, as compared to the incumbent PEM technology. Our silicon based fuel
cell has demonstrated higher power density than PEM technology, can operate with
and without air, uses traditional chip manufacturing technology, and in volume
production is expected to provide a very cost-effective solution. We are proud
to use this disruptive technology to build products for Hobie Cat and EKO
Vehicles, and other potential customers," said Dr. Chris D'Couto, President and
CEO.
