I have finally completed the drawings of my cell. I have been using 304 stainless because I can get it at the local sheet metal shop as scrap peaces (VERY cheap). I have received 316 and am building the cell with it to see how much difference there is. I found that with the 304 plates, the rip-stop nylon  tends to start clogging up after about 1200 hours of operation. I assume this is the carbon that comes from the 304 stainless. With the cell re-built with 316 stainless, there may be less to clog the nylon.

 

Here are the links to my drawings.

This design is based on the Bill Williams video.

The 1/4" gas holes might be too small and you might end up with too many gas bubbles between plates.  Just an opinion.

good work Gene

 

Might pay to make the holes of the plates1/2 inch and gaskets 3/8 inch. That way the  edges of the plate will be less exposed to current leakage. The gaskets will compress into the hole, nearly sealing them.

I think that is the right idea. I have made the hole in the new plates 5/16 so that the 1/4 hole in the gasket will tend to seal the edge of the plate hole. If I make the hole any larger, there could be less area of gasket to seal the area to the edge of the plate. I want to keep the plates 4" square and still get as much active area as possible.

In reading your posts, I think you are running diesel. I will be using the cell with my gas car. I still don't know how much hydrogen is needed. If more hydrogen is needed than I am planning for, I may need to go to larger plates.

I am having small problems with electrolyte being sucked into my first dryer. I think it has something to do with the turbo when it is on boost. Am looking at away to reduce this so I cannot help with any sort of figures at present

Check out Peter James  at www.myhydrogencar.com.au . He has installed units on petrol and diesel cars

Looks good Gene

One thing that I found was that the larger port allows the cell to breathe, also glad to see that folks recognized the roll of the gasket in sealing or reducing parasitic losses.

For those that have not seen the GSC build or operation please review the videos...

My YouTube videos can be accessed at "vipond50" on YouTube.

BTW...Peter, Reg and Dracy are doing excellent work with this design style also, so they are an excellent resource to draw upon.

Best regards

Bill Williams
