Comments Regarding my Fuel Cell Design
and Analysis Work:
-
- I was very fortunate to be introduced to a fuel cell startup company,
Neah Power Systems, inc., in 2000. For about
7 years I did a variety
of fuel cell related design work. This allowed me to learn a fair bit
about electrochemistry, microfluidics, piezopumps, switchmode power
conversion and chemical resistant seals, adhesive and structural materials.
I was also able to hone my mechanical design skills and become expert with
SolidWorks, a powerful CAD tool.
-
- I also got involved with the fuel cell safety and regulatory process.
For a while I was on US Fuel Cell Council and Underwriter Laboratories
committees set up to develop guidance for fuel cell manufacturers. It
is fascinating to be part of this process for a new industry, and I value
this experience.
-
- All said, the single most valuable skill I came away with was the
ability to use finite element analysis (FEA) to perform a wide range of
"numerical experiments." These experiments greatly aid understanding
of complex
thermal, mechanical, electrophysical, fluidic and electrochemical problems.
-
- I now routinely use FEA to "scout out" the nature and magnitudes of
forces and other physical or chemical field parameters before I attempt to
design and make a real piece of hardware. This "knowing before going"
that I get from FEA numerical experiments saves huge effort in the long run
and often gives helpful insight into the underlying physical nature of a design
problem.
