Holiday project

[Hidden]

Made some modifications to the cell, added a new bubbler and water reservoir. Also used a working flashback arrestor out of aquarium stone bubblers and fine steel wool. To make it even more secure in case of flashback arrestor failure an overpressure valve was added which would hopefully open in case of a slightly larger pressure than normal.
flame is working fine, when the cell warms up i can get 23V / 20A, but i'd like to have more volts and less amps. when i ever encounter a deal for ss316L plates like last time again i'll buy them.


we also have a powermeter somewhere here steve, when i have found it i'll do efficiency measurements of the power supply. i'm really impressed by this china scrap nevertheless, fan wasn't even necessary at 600-800W and it's not as warm as it could have been.

haha they are making better and better stuff all the time, kinda scary isn't it?

yes


did some measurements today, power supply can handle max. 900W, tested till 450W.


As you can see both current and power is proportional to gas output, so there is no "sweet" spot to be found, the cell (when warmed up) acts as a linear resistor.
Sadly it's only about 4.7MMW, on the other hand there are various ways gas could have escaped and not being measured.

Yes, like a resistor. However it also holds on a charge. Not comperable like a capacitor, but it does hold it.

6% KoH solution,
19V, 10A,
1liter/min


So 1l/190Wmin. Still my goal is producing 1l/min for 150W.
I'm now considering if it's worth to upgrade my cell (several issues here) or buy something which is tested already.
