Development of Alternative and Durable High Performance Cathode Supports for PEM Fuel Cells
EMSL Project ID
24990
Abstract
The poor durability of cathode supports and catalysts in proton exchange membrane fuel cells (PEMFCs) is a key technical barrier for stationary and transportation applications. Carbon support corrosion poses significant concerns at high electrode potentials and is accelerated during start/stop cycles and during higher temperature operation (>100°C). Graphitized supports show better but still insufficient corrosion resistance. To address the critical issues associated with the carbon support, we have assembled a strong multi-disciplinary team led by Pacific Northwest National Laboratory (PNNL) with participations of Ballard Power Systems (BPS), Oak Ridge National Laboratory (ORNL), and the University of Delaware (UD). The goal is to develop and evaluate new classes of alternative and durable high-performance cathode supports for PEM fuel cells.
