Amoeba Cell: Goal Reached!

[BoyntonStu]

I ran the Amoeba Cell for several runs with additional NaOH added after each run to raise the current.

The Amoeba Cell finally produced 1 Liter in under 60 seconds (55). Based on 55 seconds/L and 14.6 Volts and 10 Amps the MMW is 7.25.

By the time I got the camera set up, the cell cooled down a bit and its performance fell off to 70 seconds/liter at less current.

The cell measures 2x6x1 or 12 cubic inches!

Is the 12 cubic inch Amoeba Cell the smallest 1 LPM producer?

Nice Stu!

Remind me, how many plates were in this particular cell?

7+ MMW is impressive!

Russ,

15 2x6 plates. Center is positive.

There is much wasted cell area due to the 1/4" wide gaskets.

The actual generating area is 1.5 x 5.5 = 8.25 sq in

The Amoeba Cell should be made from 3 x 6 plates; 2.5 x 5.5 = 13.5 sq in

An area gain of 63% by just using an inch wider plate.

Here's an Amoeba Cell built by Tom, an Amoeba enthusiast, that he made out of 3 x 6 plates.

Hi Stu,

This answers one question... looks like size does not matter. (or does it!!)

Do you know how much NaOH you are using % wise?

Shane,

Sorry, I just keep feeding the reservoir like you would feed a baby, a spoonful at a time.

I add NaOH and watch the current rise.

BTW After the electrolyte is warmed up, the NaOH dissolves very fast.

To assist the process, I raise the reservoir in order to pump lots of electrolyte.

It's not the size of the ship that matters, it's the motion of the ocean.

I have to add that I've had these same thoughts, surface area is useful but I think there is a limit where space on a single plate becomes waste. Current, as we all know, takes the path of least resistance, therefore, what reasoning does it have to travel all over a plates surface in equal strength before jumping across to it's cell neighbour?

A comparison to support the above:

RadGenH2O on youtube has a 25 plate 6"x6" sid cell design dry cell, he constantly achieves a 5.4 to 5.5 MMW when running with 5 neutrals. My own 25 plate design also has 5 neutrals on switch plate covers, my surface area per plate is a lot smaller yet I consistantly get the same MMW.

If we were to build two cells, one with 13 plates at 6"x6" and one with 26 plates at 3"x6", my money would be on the latter.

You're such a tease Shane...
