Honda has already been doing this in Japan, using a FCEV to provide whole house power for long periods of times. I saw an article on this from at least a year ago.
Whether a battery or fuel cell is better suited, I don't know. Either way, it's very exciting for potential use on very hot days - better than using a peaking power plant.
