Low platinum loaded graphene based electrode layers for PEM fuel cell

Official URL: http://abstracts.acs.org/chem/248nm/program/view.php

In our study we aim to increase platinum (Pt) utilization through an enhancement of the three-phase boundary of electrode layer to reduce the use of valuable Pt catalyst and cost of PEM fuel cell. Thus, Poly(vinylidene fluoride) (PVDF)/graphene oxide nanofiber composites are produced according to the electro-spinning technique, then Pt is deposited onto the nanofiber mats in chemical reduction. It is expect that electrospun structured Pt/graphene plays an important role as catalyst support by mitigating CO poisoning risks and reducing cost. The ex-situ tests of resultant gas diffusion electrodes is accomplished by scanning electron microscope (SEM), transmission electron microscope (TEM), and electrical conductivity according to four-point probe technique. As conclusion, to be able to compare with commercial applications, MEAs is prepared from our electrodes will be tested in PEM fuel cell.
