- W2314116502 abstract "Performance and durability of cathodes have been one of the main factors impeding commercialization of fuel cells for automotive applications. This work reports an optimized Rotating Disk Electrode (RDE) technique and a mass activity and durability for a baseline Pt/Graphitized Carbon (Pt/GC). An accelerated stress test (AST) is performed to determine the durability of the catalysts by cycling 30,000 times between 0.6 and 1.0V with a 1 sec hold at each potential. Mass activity and electrochemical surface area are measured at the beginning of life (BOL) and at the end of life (EOL) after 30,000 cycles. The BOL mass activity of the Pt/GC baseline is 218 A/g-Pt. In-house prepared Pt-Ni-Co ternary alloys show a BOL mass activity of 600-900 A/g-Pt for the best performing catalysts not shown in this report. However optimization of post heat and acid treatment of catalysts is necessary to improve the durability. The optimum temperature for the initial and final post heat treatment is found to be 400 oC for the ternary alloy catalysts. The heat-acid-heat treated catalyst is more durable showing a 52% degradation rate (EOL: 292 A/g-Pt) compared to 75% (EOL: 196 A/g-Pt) for the heat-acid treated catalysts." @default.
