Dear All

I am recently conducting research on the use of PTFE as a catalyst binder applied to carbon paper. The catalyst I use is Platinum. When I did the OCV test on the electrode I made, the voltage produced was very low. The OCV value can only reach 0.5V and continuously decreases to 0.1 V.

My question: Is there a special stage or treatment in using PTFE as a catalyst binder? Because when I use Nafion as a catalyst binder, the OCV value is 0.9V (normal value).

Thank you for your kind attention
