Well, we are making a little progress in that the cell is sealed now.  I built an assembly of clamps and placed aluminum angle around the outside edges to help it stay flat and not flex.  I found out when doing tests using air, that pressure tests are out of the question.  The cell walls actually expand almost immediately upon adding the air and the wall dividers seperated from the outside edges of the tank.  So while we should be sealed well enough to do our bubble tests, I don’t think we will be able to do any real pressure tests.

A couple observations and then I’ll show the video clips. 

Plates versus Pipes:

I’ve done the surface area calculations on my pipes and here is the math.  Please check and make sure I’m not doing something wrong here:

Anode: 1.25 OD 5″ long: 2(pi) * (1.25/2) * 5 = 19.63 per pipe * 6 pipes = 117.78 square inches

Cathode: 1.42 ID 5″ long: 2(pi) * (1.42/2) * 5 = 22.31″ per pipe * 6 pipes = 133.86 square inches

If you remember from an earlier post, the plates have a surface area of 12.48 square inches per plate.  Doing the math it would appear that I need a 12 plate unit to have the same surface area as my pipe design and I plan to start building that in the next week or so.

So, here are the videos of the completed cell along with a few small tests.

Test-033:  This is a cell construction video to show the finished cell with its lid and connections.

Test-034:  This video shows the cell connected normally with anode (inside) and cathode (outside ).

Test-035: This video shows the cathode connection bolt and how its creating hydrogen itself.  Which is rather confusing to me as to how or why its doing this.  It would appear that we should be generating off the outside of the tubes as well if its reacting to the bolt like it seems to be.  But we don’t see this…

Test-036: Now we’ve reversed the anode and cathode connections to see if there is any difference as to which tube ends up being the largest.  Can you tell?

Test-037: View from the top of the cell (bubbles) with the first being normal hookup with cathode being on teh outside tubes and the second half of the video with the outer tube being the anode.  One thing to note however is the water color.  You will see the water almost instantly start turning a darker yellow when I reverse these connections.  I don’t know if the water reaches a point where it does this on its own, or if it has something to do with the connections.  Will need to do further testing…

I’m not sure which configuration performs the best between the inner and outer tubes being anodes or cathodes.  Here is a short video clip that cycles back and forth a few times but I didn’t do a very good job of keeping the same perspective so its hard to tell.  I’ll try to do a better job of video taping it later this weekend and see if we can tell which is best.

Test-038: Cycles back and forth between anode and cathode being the outer tubes.
