摘要

Environment-friendly proton-exchange-membrane fuel cells (PEMFC) are considered a possible answer to environmental and energy problems.To make fuel-cell automobiles a reality,the activity and life of the Pt/C cathode catalyst must be improved.Towards this goal,we have developed a novel time-gating quick XAFS (QXAFS) technique with 1-s time resolution and an energy-dispersive XAFS (DXAFS) system with 4-ms time resolution.
