The electrocatalysts and supports thrust is studying catalysts, catalyst supports, and their interactions to enable advanced platinum-based catalysts to achieve technology-enabling performance and durability.
1Electrocatalysts & Supports
The materials studied by FC-PAD include state-of-the-art commercial catalysts; catalysts and supports arising from materials development projects within the Fuel Cell Technologies Office and Office of Basic Energy Sciences portfolio, where sufficient quantities are available; and materials that have demonstrated the ability to reach the U.S. Department of Energy beginning-of-life performance targets or those demonstrating the potential to meet the targets in ex situ measurements.
FC-PAD is researching catalyst and catalyst support durability and degradation mechanisms to:
FC-PAD is researching catalyst and support interactions to:
FC-PAD is researching ex-situ analysis of catalyst instability on cathode catalyst layer properties to quantify the impact of catalyst degradation on the properties defining the performance of the cathode catalyst layer—for example, the impact of base metal leaching from platinum alloy catalyst on proton conductivity, oxygen permeability, and water uptake in the ionomer.
