Recent advances in fuel cell technology at Ballard

摘要: Abstract This paper presents an overview of some the key challenges and issues that need to be overcome in area performance durability achieve commercial-viable PEM fuel cell technology 1 . While there has been significant progress towards these objectives last few years, fundamental understanding factors resulting loss materials degradation is still lacking. Several elements overcoming challenges, such as situ diagnostic tools, modelling simulation accelerated stress tests are discussed. A general framework for improvement presented order US DOE cost target USD 30 k W net − stack, while advancing operational imperatives freeze start, higher temperature operation reduced reliance on external humidification.
