I have been reading up on these cells on and off for a few years now. Always wanted to make one just never had time. I am between jobs and decided to give it a try and make a cheap wet cell. Wanted to make a dry cell but can't find any stainless plate and just want to do it cheap first to play around with the concept. I went with the design that uses the stainless switchcovers. I have it set up + NNNNN - and I am not getting ANY production AT ALL connecting it to a 12V car battery. I used a nylon bolt with rubber spacers to hold it all together, submerged in distilled water. I am stumped (and new lol), what could possibly be my problem? I know its something simple. Thanks.
