In particular, tests were performed for the original configuration, hydrogen inlet and outlet reversed, air inlet and outlet reversed, and hoses reversed for both gases The operating conditions for all gas configurations were pressure of 0.5 bar, temperature of 65 °C, anode and cathode relative humidity of 60 %, and anode and cathode stoichiom etry of 1.3 and 2.5 respectively. The tests performed were the polarization curve (PC) for each gas configuration and the dynamic load cycles (FC-DLC) also for each hose position. Acurrent density mapping (CDM) sensor, capable of measur- ing both the current density distribution and the tempera- ture distribution inside the cell, was inserted into the fuel cell system during all tests. The use of the sensor during the experiments makes it possible to know how these distribu- tions behave and to observe whether or not there is homo- geneity in its measurements, thus verifying that the design of the flow channels is adequate and fulfilling its function. The results can be used to investigate and compare other bipolar plates and channel designs, or to compare with results from other test benches and environmental conditions.application/pdf19 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/PEMFCPolarization curveDynamic load cycleCurrent density mappinginfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1016/j.dib.2024.110392
