While I fully agree that a fuel cell for a car is foolish, the one limitation of batteries is energy density. In those applications where energy density is the MOST critical factor, such a LONG distance ocean and air travel, H2 makes sense as it has 7 times the energy density of batteries. Yes, it is inefficient, but it does make long distance travel carbon free, which batteries cannot do.
