At 20.2% combined efficiency, you could use traditional PV cells and come out ahead. Use the power generated for electrolysis if you really need some hydrogen.

Still, it'll be neat if they come up with a more efficient flavor. That'd be good in a car in the winter (Electricity to run the motors, hydrogen to run a little internal combustion engine for cabin heating and battery charging). The cabin heater is a bit of a weak spot for electric cars.
