flatsville, the fuel cell concept has merits and can be very efficiently employed in certain fields and as backup power. Until they find a way to produce very cheap hydrogen their future is limited.

About a year ago I was thinking of starting a company in this field. Unfortunate the more efficient cells work at quite high temperatures an their life span is short due to corrosive effects.

The soft membrane concept employed by BLDP is not as efficient but works at reasonable temperature. Unless natural gas will be priced cheaper per BTU, than coal or oil I do not see a lot of fundamental gains in energy production versus the modern gas turbines who got up to 60% efficency. (10-15 years ago the eficiency of power plants was in the 35% to 40% range)

The new ceramic internal combustion car engines are also very promising.

Therefore fuel cell can not effectively compete with electricity and their use will be limited.

Those are my two cents
