Solution combustion synthesized ceria or alumina supported Pt as cathode electrocatalyst for PEM fuel cells
Abstract
Current status of the Proton Exchange Membrane (PEM) fuel cell (FC) technology, exhibited its penetration in the commercial market of electric vehicles; however, it is lacking the factor of a long lifetime due to the fact that its cathode catalysts are prone to degradation and requires immediate attention. In this investigation, we propose a synthesis strategy where oxides will act as support for Pt catalyst and optimize the mixing of high-surface-area (HSA) and porous support with Pt to achieve a sufficient electrical conductivity in resultant Pt/support mix. The use of durable HSA oxides as support instead of HSA carbon will avoid the degradation issue. By varying the preparative parameter of the solution combustion synthesis method, we successfully synthesized Pt supported on cerium oxide (ceria) and Pt supported on aluminum oxide (alumina) samples with different Pt loadings. Among Pt/ceria and Pt/alumina composite samples, 80 wt% Pt on ceria and 90 wt% Pt on alumina showed relatively better mass-specific activity (MSA) of 52 mA/cm 2 and 85 mA/cm 2 , respectively and are far less than that of commercial reference catalyst (BASF MSA = 143 mA/cm 2 and HiSpec9100 MSA = 169 mA/cm 2 ). Durability investigation on Pt/alumina composite showed that as the Pt loading is increased, up to 70 wt% Pt on alumina, the catalyst showed improvements instead of degradation while as Pt wt.% increased further, i.e. 80 wt% or 90 wt% Pt on alumina, the degradation curve followed the trend of that of commercial reference electrocatalysts. Finally, when microstructural features are compared to a reported catalyst with similar features, which was used for PEM based electrolyzer, it is concluded that to realize true performance, it is necessary to evaluate the synthesized catalyst in a fuel cell instead of characterizing it with thin-film rotating disk electrode (TF-RDE) technique.
