I took a two hole stopper and used a drill press to drill the third hole for my system.
The more reactive the materials, the more spectacular the failures.
The testing isn't over until the prototype is destroyed.

Really an informative post since it is so difficult to get compressed deuterium gas! Good details, too.

The fuel cell is the exact one my daughter used for her "hydrogen" powered mini-model car (worked very well.) She had/used a solar cell to create the hydrogen (& oxygen) gas.

What could be greener than H2 fuel made by electrolysis, using electricity from PV cells?
But people using lots of H2, such as for oil refining or ammonia-making (space shuttle fuel tanks were a drop in the bucket) know that
"Today, 95% of the hydrogen produced in the United States is made by natural gas reforming in large central plants."
Ref: http://energy.gov/eere/fuelcells/hydrogen-production

So electric cars powered by hydrogen fuel cells are just a more efficient fossil-fuel-driven technology.
But way cool, and hobby-scale PEM cells are a fringe benefit.

I'd say this is realted:
http://fuelcellstore.com/fuel-cell-stac ... -fuel-cell

Cheap, "reversible" (well all of them are really...maybe it's made to be more compatible (separate water fill inlet or something) with reverse operation? Not sure) PEM cell. 7 ml/min (claimed), not the fastest thing out there, but if you use a reservoir as suggested here, it can produce all the deuterium you need, on the cheap.

Indeed seems to have a separate (third) port for filling...?

Glad to have found this thread, as I'm planning on using heavy water as well. 10 liters of D2 would cost me a whopping 280 USD...No thanks. I can get that from about a gram of D2O.

Nice finish on the item.

Really nice! Are you going to put in a float switch or equivalent which will allow auto-demand?

Hadn't thought of that, but I like the idea! Thanks!
