[Analysis Case] Evaluation of Metal Valence of Fuel Cell PtRu Catalyst Under Atmosphere and Temperature Control
Evaluation of chemical states under conditions where gas atmosphere and temperature are controlled is possible.
Carbon-supported PtRu (PtRu/C) catalysts are used as anode (fuel electrode) catalysts in fuel cells. There is a demand for reducing the amount of Pt used in order to lower costs, and active research and development is underway. To evaluate the state of the catalyst under fuel cell operating conditions, in-situ XAFS, which allows for observation in the same environment while controlling the gas atmosphere and temperature of the sample, is effective. This document presents a case study where the valence states of Pt and Ru in PtRu/C catalysts were evaluated using in-situ XAFS in an environment controlled to the gas atmosphere and temperature actually used in fuel cells.
