Materials of Construction for Hydrocarbon-Air Fuel Cells with Hot Concentrated Phosphoric Acid Electrolyte

摘要

The results of chemical and electrochemical corrosion studies of selected massive metals, alloys and carbons in 90 Wt. % phosphoric acid (C. P. grade) at elevated temperatures (150-175C) are presented. Also, the data for the behavior of selected plastics in the concentrated acid as well as in the typical hydrocarbon fuel,JP-4,at elevated temperatures are presented.
