HIGH SULFUR-TOLERANT Pt/Ce_(0.8)Gd_(0.2)O_(1.9)CATALYST FOR LIQUID HYDROCARBON FUEL PROCESSING IN PEMFC APPLICATIONS

摘要

Proton-exchanged membrane fuel cells (PEMFCs)are a preferred fuel cell technology for many transportation applications.Until a widespread H2 refueling infrastructure exists,on-board reformation technologies are needed to convert high energy density commercial grade liquid hydrocarbon fuels into H2 for PEMFCs.A significant challenge conflicting these efforts is the development of high efficiency fuel processing catalysts that have to be active,selective,durable,and tolerant to sulfur and coke.
