The only application where I've seen fuel cells used for solar electric 
storage is in space, where I presume the weight penalty of conventional 
batteries makes the difference.

In any case, adequate, even practical systems already exist using conventional 
batteries instead of fuel cells, so if you're interested in this there's no 
reason not to go ahead and do it.
