Journal ArticleDOI
Effect of voltage on platinum dissolution : Relevance to polymer electrolyte fuel cells
TL;DR: In this paper, the long-term dissolution behavior of polycrystalline platinum and high-surface-area carbon-supported platinum particles was studied under potentiostatic conditions relevant to PEFC cathode conditions.
Journal ArticleDOI
Stability and Dissolution of Platinum Surfaces in Perchloric Acid
Vladimir Komanicky,Kee-Chul Chang,Andreas Menzel,Nenad M. Markovic,H. You,X. Wang,Deborah J. Myers +6 more
TL;DR: In this paper, the stability and dissolution of single-crystal surfaces were investigated with atomic force microscopy and inductively coupled plasma mass spectrometry, and a clear difference was observed between the large low-index surfaces and the nanofaceted surfaces.
Journal ArticleDOI
Bimetallic Pd–Cu Oxygen Reduction Electrocatalysts
TL;DR: A series of carbon-supported Pd-Cu catalysts with various molar ratios of Pd to Cu was prepared by co-impregnation followed by a reduction in a hydrogen atmosphere at three different temperatures as mentioned in this paper.
Journal ArticleDOI
Effect of CO and CO2 impurities on performance of direct hydrogen polymer-electrolyte fuel cells
Rajesh K. Ahluwalia,X. Wang +1 more
TL;DR: In this paper, a poisoning model was developed to determine the accumulation of CO and CO2 impurities due to anode gas recycle in fuel H2 for a specified maximum acceptable degradation in cell voltage and stack efficiency, where the impurity limits are functions of operating conditions such as pressure and temperature, and stack design parameters, such as catalyst loading and membrane thickness.

Oxygen ion conducting materials
TL;DR: In this article, a dopant was added to the host perovskite lattice of (La,Sr)MnO 3 to induce oxygen ion vacancies to form in the lattice.
