"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."
I don't as a sailor agree with this engineering solution. Lithium batteries are heavy enough to provide ballast. The solar panels more efficiently recharge that battery. It could in effect be a an infinite motive solution. The fuel cell will have to be refueled externally unless the solar system is big enough which may be self limiting due to the inefficiency of fuel cells. They also won't supply as much ballast. But the upside is the boat won't sink due to all the hydrogen tanks. Lawrence Rhodes. -------------- next part -------------- An HTML attachment was scrubbed...
