Short presentation

Sapere Aude DFF-Forskningsleder project

The fundamental processes of fuel cell catalyst degradation

The work is funded with the grant# 10-081337 of The Danish Council for Independent Research | Technology and Production Sciences and The Danish Council for Independent Research | Natural Sciences

The aim of the project is to identify the main mechanism for fuel cell catalyst degradation, develop strategies for its mitigation, and to synthesize degradation resistant high surface area catalysts.
