Increasing the performance of electrode by using the multi-wall carbon nanotube at microporous layer of gas diffusion electrode in polymer exchange membrane fuel cell

In this work, the effect of multi-wall carbon nanotubes (MWCNT) at micro porous layer (MPL) on electrode performance was studied. We utilized different percentages of MWCNT and VulcanXC-72R at the MPL of gas-diffusion electrode (GDE) with same Pt loading in the catalyst layer. The performance of the electrodes in Oxygen reduction reaction (ORR) is tested and the structure of MPL is distinguished by different techniques Our results indicate that MWCNT at MPL makes the performance of GDE increases since the following condition exist 80 wt% MWCNT and 20 wt% VulcanXC- 72R with Pt loading 0.5 mg.cm-
