Impact of Exhaust Water Acidity on Nafion Membrane Proton Conductivity at Operating Temperatures above 1000C

Abstract

The purpose of this paper is to examine the impact acetic acid, added to exhaust water, had on the Nafion membrane proton conductivity degradation behavior when heated at elevated operating temperatures. These results will be contrasted against Nafion membrane proton conductivity degradation results after being heated using elevated operating temperatures, without acetic acid being added to the water. Multiple formulations of Nafion exist such as 112, 211, 212, NE1035, 115, 117 and 1110, to name a few of the more common formulations.
