This is only an indirect answer. MIT has a course on "Application of
Technology" in which fuel cells are analyzed. The 'theoretical' FC
efficiency depends on the load. In slide 9
(http://web.mit.edu/1.149/www/lecture21/lec21slides.pdf) the efficiency
varies from 100% at no load to 50% at full load. In slide 26 the
'typical' efficiency is given as 45%. This probably corresponds to a
range of load conditions encountered during driving, but I am not sure.
A tradeoff for higher efficiency vs larger FC size would be possible.
The optimum may be to increase the size to achieve an efficiency in the
60-75% range.
How can something be 100 percent efficient at no load?
The only possible efficiency at no load would be zero.
