TL;DR: In this article, the authors have shown that graphitization at 1600°C is an optimum temperature among 1100, 1600, and 2000°C to obtain the highest durability for Pt/C catalysts.
Journal ArticleDOI
Preparation of Pt/mesoporous carbon (MC) electrode catalyst and its reactivity toward oxygen reduction
TL;DR: In this article, high-structurally controllable mesoporous carbon (MC) support was synthesized through self-organization of surfactants and carbon precursors, followed by carbonization.
Journal ArticleDOI
Molecular Structure of Buried Perfluorosulfonated Ionomer/Pt Interface Probed by Vibrational Sum Frequency Generation Spectroscopy
TL;DR: In this article, the real thickness of perfluorosulfonated ionomer (PFSI) films was analyzed by spectroscopic techniques and simulation modelings with molecular insights.
Patent
Electrode catalyst for fuel cell and fuel cell using the same
TL;DR: In this paper, an electrode catalyst for a fuel cell, which can be produced with high efficiency by a simple process without the need of using any silica template unlike a conventional one, has a relatively large mesopore size (5 nm or more), can carry a catalyst particle in its pores stably, and can exhibit a highly developed triple phase boundary state readily.
