It is HUGELY cheaper and one can make them serve both heat and power (CHP).

If the fuel-cell tech is not sufficiently low-tech, ICE-s may be an even better choice for developing countries where servicing ICE engines may be easier/cheaper.

If this artificial leaf is 10 times more efficient, than we talk about at least 30% efficiency which would be GREAT especially if we consider the average PV efficiency (~15-20%) and the fact that here you get hydrogen out of it which may become possible to store cheaper than electricity directly.

The article seems to be sloppy at places. You obviously don’t “store” hydrogen and oxygen in a fuel cell, but you react them in the fuel cell to get electricity. One stores hydrogen in special storage tanks.

The article doesn’t talk too much about the biggest weakness of hydrogen based systems: the fuel cell. They are still very expensive. Until the Bloom Box or other fuel cell technology doesn’t come down significantly in price, hydrogen based systems will not become viable. Not to say that this is not a great advancement, only I don’t see the “viable” system it talks about.

Bloom Energy should buy into this research heavily because it would eliminate the greatest weakness of their system, that they need natural gas as the source of hydrogen. If they had a completely renewable hydrogen source their system would be THE solution.
