Nobel metal air battery fuel cell update

Support NatureHacker with Fluoride Free Tooth Brushing Formula

So in making a high power battery you need two sides, a reductive side (anode) and oxidative side (cathode).  This time I got a real salt bridge to try out.  My last salt bridge was a rolled up napkin.  This one was hydrochloric acid plugged up with some glass wool.  Unfortunately while I got great voltage with h2o2 on cathode side (1.35 v) I got almost zero amps, 10 mA.  This means our bridge just wasn't great, it must be too long.  However the glass wool seemed to work great in preventing the two solutions from mixing.  For our high power battery we will need a much shorter salt bridge.  I will try taping this one up well and cutting it down to size but what I will probably have to do is actually make an H cell or make a big fritted glass divider to divide oxidative from reductive in the same cup.  I wanted to try a combo of N2O and Oxygen using the dispersion tube for the oxidative cathode side (seen on the left side of my pic) but my balloon to hold the gasses broke.  Instead I just used h2o2 which is good for testing.  BTW this is a copper rhenium air battery currently, eventually it will be copper iridium fuel cell (oxidizer on one side reducer (like hydrogen) on the other) which is best.  Also you can make this a solar cell by making the anode (copper) side filled with photosensitive dyes like chlorophyll or blackberry juice and shining light on it.
