Fuel cell powered sailboats?

A.G.O. Environmental Electronics is experimenting with a fuel cell powered sailboat. Victoria News reported on the initial tests, which were somewhat disappointing. The initial predictions hoped for a high-end output of 6 kts, but actual results were 1.5 kts from a 300 watt Horizon fuel cell set up. (Image below)

Although the resulting speed was dramatically less than predicted, no discussion is presented regarding the actual motor used. Maybe it was a trolling motor? I remember reading about a German or Danish couple who were cruising with an inboard electric motor system solely powered by solar and wind generators, so it a more aggressive power plant might resolve the problem.

On the third hand... who cares about powering with electricity? what about just for electrical generation?

Marine Fuel Cell

I seem to remember the Cdn Coast Guard did an R&D project a few years ago with the Ballard fuel cells they use to power commuter bus's. Don't think it worked out too well.

300 watts is almost enough to feel something but not excited.

Fuel cells are a good idea, but aren't quite there yet, at least for the guy on the street.

The big issues with fuel cells are:
- upfront cost
- you need a source of hydrogen
- longevity.

Fuel cells can produce as much electricity as one would need, at a cost.
The stacks will deteriorate as time goes by, which means you have to pretty much buy new fuel cells, big$$. The longest I've heard a stack last is 5 years, that isn't a long time considering the cost. Maybe they last longer now, however I doubt much longer.

And those little electric motors for the cooling fans, as shown in the picture above, how long do think they will last in a marine environment?

Hydrogen ??? on a boat???

They do sell a C3 powered fuel cell, but it is only about 15% efficiency less than most internal combustion engines.

My inverter to charge all the electrical gizmos is 140 W.

Sorry needs work.

My cabin has 2X110W and a 1X85 watt solar panel, they can't quite keep up to an efficienct fridge, with day to day lighting etc.

I thought sailboats were wind powered?

300 watts would produce less than 1/2 horsepower, even assuming a 100% efficient system. I'm surprised they expected 6 knots but you have to admire their optimism!

If they really expected to achieve 6 knots, you might admire their optimism, but perhaps not their engineering skills.
