Fuel-cell membranes - breakthrough or pie-in-the-sky?

Conno >

Interesting, I see it now mitigates one of the three risk factors which is why you were anticipating the announcement.

Re reading the announcement on the 15/12, I noticed :-

* Methanol crossover at open circuit voltage (OCV) now stands at approx 57 mA/
cm2, slightly above previous levels, but still significantly below that of
fluorocarbon membranes;

As you may realise that I have only just started looking at this subject. Does that still represent fluorocarbon as a threat as well as Li Ion developments?
