I notice that such things as 'Nafion and Platinum' are needed for the construction of a PEM fuel cell and wonder if any of you are aware of any cheaper substitutes that could be used?

Thank you both for your speedy responses. I will try to get another medium (sodium hydroxide, or dilute sulfuric acid) rather than the normal table salt that I am presently using. Would this then provide pure Hydrogen & Oxygen? I will still need to find a suitable way of separating the gases without the severe lack of production that I am getting at the moment. I don't want to collect 'Browns Gas, HHO Gas, Oxyhydrogen Fuel) as I am fascinated by the Hydrogen fuel cell technology I recently read about and to experiment I would need pure Hydrogen and would rather use concentrated Oxygen rather than than use the surrounding air. I will check the link (Hoffman voltameter) Thank you again.

Hi I offer my apologies if the answers to my question are already in the forums and would like to take this opportunity to 'Hi' as I have only just joined as a member. I have been experimenting with electrolysis and and have enjoyed much of the information that I have gained from reading the threads here.... but! I would like to separate Hydrogen and Oxygen and seem to be having some problems. 1. If I use a brine solution then it appears I am only getting Hydrogen and Chlorine and not the Oxygen I require. 2. When I put any sort of divider between the diodes so as to keep the gases separate then I seem to get very little activity in producing anything. Any help would be greatly appreciated.
