We are headed towards a society that will be largely unplugged – from fossil fuels, wall outlets, etc. – but this relies on the portability of the power system. What we are trying to do is to bring the revolution of electrochemical energy conversion storage.
A battery is an energy storage device. Fuel cells, however, are energy conversion devices. They allow the conversion of chemical energy to electrical energy. We are working to develop high performance fuel cells using the most efficient and cost effective materials.

This sounds great except H2 fuel cells are only around 25% eff from the base fuel the H2 is made from vs batteries which are 80-90% eff from the same electricity used to make the H2.
Yet they didn’t bother to mention this deal breaking fact. Fact is a regular ICE can be more eff than a as those who know call them, fool cells.

We’ve been using ICE’s for 100+ years and have been improving their efficiency during that time. Do you think that a similar improvement could occur with PEMs?
