I need to derive useful power from a couple of PEM fuel cells for a 
project. Each cell can go as low as 0.5V under load, so I will use two 
in series (three is possible, but two would be better). I'd like an 
adjustable converter to increase the voltage to 5V-ish and less (so I 
can mess around and power different things from it).

I was looking at something like this:

datasheet:

anyone have a better idea?
