The Effect of Common Airborne Impurities and Mixtures on PEMFC Performance and Durability
Abstract
This work reports the performance and durability effects resulting from exposing the cathode of a hydrogen proton exchange membrane fuel cell (PEMFC) to air containing benzene (BZ), sulfur dioxide (SO2), and nitrogen dioxide (NO2) at concentrations ≤ 2 ppm for single impurities and in mixtures. This is the first phase of a project to deploy fuel cell powered buses in Hawai‛i Volcanoes National Park (HAVO). The data reported herein is obtained from 50 cm2 single cells and will contribute to the future development of: (i) performance specifications for air filtration media used in fuel cell buses, (ii) a fuel cell stack model that predicts performance when impurities are present, and (iii) operational protocols for the system used to control the PEMFC stack.
