However, the persistently high costs and complexities of the PEMFC and the SOFC have led to renewed interest in the AFC in recent times. This work reports the designs of custom test fixtures and electronics instrumentation relevant for AFC electrode testing and system optimization. Features implemented in the designs include a real-time voltage measurement unit (VMU), electronic load circuit, and electrolyte heater system. Validation experiments indicated a close agreement between the VMU’s readings, Nernst equation predictions, and readings from a digital voltmeter. The electrolyte heater system’s temperature measurement module was validated with its ability to replicate a cooling profile of ethanol similar to that obtained from a mercury-in-glass thermometer. Materials selection, design considerations, and fabrication steps for other test station components, such as the button-cell test apparatus and the half-cylinder electrolyte heater, were presented. The test station was used for polarization studies of aluminum-air AFC under different conditions of potassium hydroxide (KOH) electrolyte temperature and concentration. The studies revealed optimum values of electrolyte temperature and concentration for the AFC electrode to be 70 °C and 4 M KOH, respectively.","PeriodicalId":15829,"journal":{"name":"Journal of Fuel Cell Science and Technology","volume":"1 1","pages":"024501"},"PeriodicalIF":0.0,"publicationDate":"2015-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1115/1.4029421","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63488235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Continuous tests with H2 and simulated reformate which was composed of H2, water steam and methanol as the fuel were performed on both single cells. 12-h-startup/12-h-shutdown dynamic tests were performed on the first single cell with pure dry H2 as the fuel and on the second single cell with simulated reformate as the fuel. Along with the tests electrochemical techniques such as polarization curves and electrochemical impedance spectroscopy (EIS) were employed to study the degradation mechanisms of the fuel cells. Both single cells showed an increase in the performance in the H2 continuous tests, because of a decrease in the oxygen reduction reaction (ORR) kinetic resistance probably due to the redistribution of PA between the membrane and electrodes. EIS measurement of first fuel cell during the start/stop test showed that the mass transfer resistance and ohmic resistance increased which can be attributed to the corrosion of carbon support in the catalyst layer and degradation of the PBI membrane. During the continuous test with simulated reformate as the fuel the ORR kinetic resistance and mass transfer resistance of both single cells increased. The performance of the second single cell experienced a slight decrease during the start/stop test with simulated reformate as the fuel.
