H2/O2 seperation membrane with electrolite
H2/O2 seperation membrane with electrolite
(OP)
Hello all,
I'm wondering if anyone has information on what membrane I might use to seperate my electrodes in an electrolite solution so that I can get H2 off of one electrode and O2 off the other electrode in an electrolyzer. Therefore the membrane must allow the creation of H2 and O2 using electricity, but have the electrodes sepearated so I get pure H2 off of one and pure 02 off of the other electrode. Any help would be great as I'm a mechanical engineer and not too hot on chemistry and electrisity.

Therefore there is no need for membrane just some vessels or tubes connected to vessels placed above the electrodes, partialy encapsulating them (the bottom portion is open to electrolyte and the wires are connected from that side). Since both products are gaseous they will readily fill the vessels.

On another note, a new technology is to use an apparatus similar to a hydrocyclone to separate H2, O2, and steam. also membrane technology is generally not economic for gas separation, because of the high pressure loss across the membrane (or high capital cost), and subsequent recompression.
