摘要：

In order to improve the durability of phosphoric acid fuel cells (PAFC), it is essential tu suppl-tss the corrosion rate of carbon, which is one of the important components. In this study, we examined the influence of the orientation of carbon fibers on their corrosion rate in hot phosphoric acid. Owing to their ability to cover the surface of the graphite basal plane and thereby reducing the active site, onion-like folded carbon fiber were found more stable in hot phosphoric acid than radial folded carbon fibers, given the same degree of graphitization.
