Hi everyone! For a school project I want to use the next reduction reaction in a galvanic cell. O2 (g) + 2 H2O(l) + 4 e- --> 4 OH- (aq) (+0,40 V) But I don't know how to construct the half cell where this reaction occurs. Please, can somebody help me!

Hello I'm looking for a membrane that can pass oxygen. I know i can use teflon, but I don't know where to buy it? And are there also other posibilities? Thanks a lot!
