“Ultra-Low-Platinum Cathodes of PEMFCs”
Continuous efforts enable the hydrogen fuel cell power systems more and more competitive compared with internal combustion engine for transportation. However, the cost issue caused by the high Pt loading in cathodes of polymer electrolyte membrane fuel cell (PEMFC) must be well addressed before an extensive commercialization of fuel cell vehicles. The Pt loading should be lowered to an ultra-low level (≦0.1 gPt/kW) and several challenges are thus posed. In this study, both the electrode kinetics of oxygen reduction reaction (ORR) and O2 local transport concerning ultra-low Pt cathodes will be clarified. The influences of operating conditions, electrode structure as well as properties of designated electrocatalysts on the performance of ultra-low Pt cathodes will be examined in detail. The discussion will provide a solid scientific guideline for the application of ultra-low Pt cathodes, thus helping greatly reduce the fuel cell cost.
