Doubling deuterium production rate

Post by Dan Knapp » Wed Jun 19, 2019 5:54 pm

A recently published paper reported that electrolytic production of hydrogen could be doubled simply by placing a magnet near the anode of the electrolysis cell (https://cen.acs.org/physical-chemistry/ ... mpaign=CEN). For those making deuterium by electyrolysis, this would be an easy thing to try and could double your production rate.

Very interesting! Who will be the first among the electrolysis crowd to try this? make sure and report on it if you give it a shot.

I also wonder if this applies to all electrolysis efforts or if the lone positive +1 ion of hydrogen is just more suseptable?

Very interesting -- thanks for sharing.

The article is about electrolysis with alkaline solutions and metal electrodes, not PEM cells.
The magnet does not change the amount of hydrogen per ampere-hour of charge -- that would be impossible.

Apparently, under certain conditions, a magnetic field at the oxygen-producing electrode can as much as double the cell current, with no increase in voltage.

Hydrogen production rate, and electric power, would go up in direct proportion to the current.
Unless you reduce the cell _voltage_, the increase in efficiency is only better use of electrolyzer's capital cost and floor space.

yep
less power cost due to efficiency gain
Less heat as a consequence
This may help the hydrogen enconomy as electrolysis is not used because it is inefficient
hence the hydrocracking of Methane into hydrogen and co2 --no good for the planet but cheap hydrogen

PEM cells are, indeed, a different animal from the classic electrolysis arrangement. Thanks for pointing this out.

Turns out this is a bit more complicated that it first appeared. I just read a more detailed discussion of the paper. The anode was nickel foam coated with magnetic nickel zinc ferrite. The magnetic anode was required to get the doubling of gas production, not just the external magnet. Anyone wanting to try this should check the details in the original paper.
