Recent Advances in Materials for Fuel Cells
TL;DR: In this paper, material requirements for SOFC and PEMFC stacks, together with an introductory section on materials technology for reformers, are discussed, and it is concluded that the introduction of alternative materials/processes that would enable SOFC stacks to operate at 150-200°C, and IT-SOFC stacks at 500-700°C would have a major impact on the successful commercialization of fuel cell technology.
