My setup is a two-chamber reactor. The anode is Pt/C coated carbon paper and the anolyte is a mixture of 5M NH3 solution + 1M NaOH solution. The cathode is Pt/C coated carbon cloth with a coating of 4 diffusion layers (air-cathode) and the anolyte is 1M NaCl (though I also tried with 1M NaOH). I'm using an anion exchange membrane.
The reference electrode is Ag/AgCl placed at the anode side. The problem is whatever settings I do, the value of OCV is negative which means either the current is extremely low or no reaction is taking place at the anode side. The distance between the working and counter electrode is almost 8.5cm which can't be reduced because of cell dimensions. I'm taking anode as a working electrode because the basic purpose is to construct a novel anode material for AFC/AEC.

I'm using the freshly prepared electrodes. Is it possible that electrodes get poisoned immediately within 2 to 3 minutes of the start of the reaction?

I'm obtaining OCV values between -0.5 and -0.6 V. How the membrane swelling can be checked?- Badges
