I just again came across the Panasonic Hydrogen Home Based Fuel Cell.

Household Fuel Cell Cogeneration System | Matsu****a Electric Industrial Co., Ltd.

But I see that they are extracting the hydrogen from LPG using hot water...

This seems very inefficient compared to some of the methods that people on these forums are practicing with. Doesn't it? To know for sure I guess you'd have to know their hydrogen lpm output of the device into the fuel cell, anyone aware of the number?

Would it not be possible to purchase a fuel cell, produce a HHO unit such as one one used on this forum (Stan Meyes, Boyce, etc.) and tie it into a water source that can constantly replenish it as it goes down at a steady pace, to then run the HHO through the fuel cell and create electricity?

I think you would be able to remove most of their systems components involved in dealing with the LPG to purify it and deal with the carbon monoxide.

Here is the fuel cell: Power and Heat Generation | Fuel Cell | Matsu****a Electric Industrial Co., Ltd.


Also found some more fuel cells that can be purchased here: Fuel Cell Stacks 101W < 800W - Fuel Cell Store

All of the complete units on that website use conventional electrolysis. Has anyone here hooked up their HHO unit to a fuel cell yet to see what the outcome is?

Combine the HHO generation unit, with a proper controlled water intake system, with the fuel cell and you have Electricity generation?

I would like to know the results and I am sure many others would as well!

Addition: I just did some calculations off of P21 GmbH - Premion T Fuel Cells

And it seems (at least for their unit) you need 5.5 lpm to produce 1kw, 10 lpm for 2 kw, and 14 lpm for 3kw

This seems very feasible for some of the units I have seen people have made on this forum that output around 3 lpm, if a couple of them were joined together then you would have enough to produce adequate power generation!

Still wondering if anyone has tried connecting their home made HHO generators up to a fuel cell and what the results were? Or if anyone with more technical knowledge knows how well it would work?
