A detailed experimental study of a PEFC´s behavior considering different temperature conditions

Abstract:

Pbkp_rediction of the PEFC's behavior represents an important stage of the material and efficiency improvement. In the present work, the influence of the operating temperature for a PEFC with Nafion® 112 membrane was investigated to pbkp_redict its behavior, and empirical correlations based on experimental data were established. Voltage-current curves, power-current curves, and voltage-anode flow curves were obtained under 55 psig constant pressure at four different temperatures (65 - 80℃), and current from 0 to 24.5 A with a step of 0.25 A. A Fuel Cell Test System 850e, hydrogen, oxygen and nitrogen tanks, and a PEFC single cell were employed to conduct experimental work. By using fitting tools, correlations are proposed with coefficient of determination bigger than 0.99.
