Dataset language: English 2. Abstract: A dataset from experimental tests of a proton exchange membrane fuel cell (PEMFC) with an active area of approximately 50 cm2, parallel-serpentine channels and cross-flow field distribution between anode and cathode is presented. Tests were performed for four different gas inlet and outlet configurations. 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 ºC, anode and cathode relative humidity of 60 %, and anode and cathode stoichiometry 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. A density current mapping (CDM) sensor, capable of measuring both the current density distribution and the temperature 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 distributions behave and to observe whether or not there is homogeneity 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. 3.

File list: File name: PEMFC_Parallel-Serpentine.zip Description: Experimental data from a bipolar plate parallel-serpentine channel PEM fuel cell during polarization curve and dynamic load cycle tests. Using a current density sensor during the tests and varying the gas inlet/outlet configuration. 2. File format: Raw (file in .txt and .csv format) 3. If the dataset includes multiple files, specify the directory structure and relationships between the files: En la carpeta principal (PEMFC_Parallel-Serpentine) se incluyen 4 carpetas que hacen referencia a las 4 configuraciones de entrada/salida de las mangueras de gases. Estas configuraciones son Normal_Flow cuando las conexiones tienen la configuración original, Inverse_Hydrogen_Flow cuando se invierte la entrada/salida de hidrógeno, Inverse_Air_Flow cuando se invierte la conexión de aire, e Inverse_Flow cuando se invierten ambas mangueras. A su vez, cada carpeta se divide en 2 diferenciando entre el tipo de ensayo. Se nombra FC-DLC cuando el ensayo es el ciclo de carga dinámica y PC cuando se trata de la curva de polarización. Los archivos de su interior son 3, donde su nomenclatura hace referencia a los datos de densidad de corriente y temperatura del sensor CDM (CDM_C y CDM_T, respectivamente) y a los datos obtenidos por el banco de ensayos durante los experimentos (PC y FC_DLC). In the main directory (PEMFC_Parallel-Serpentine) there are 4 folders that refer to the 4 inlet/outlet configurations of the gas hoses. These configurations are Normal_Flow when the connections have the original configuration, Inverse_Hydrogen_Flow when the hydrogen inlet/outlet is reversed, Inverse_Air_Flow when the air connection is reversed, and Inverse_Flow when both hoses are reversed. In turn, each folder is divided into 2, differentiating between the type of test. It is named FC-DLC when the test is the dynamic load cycle and PC when it is the polarization curve. The files inside are 3, where their nomenclature refers to the current density and temperature data of the CDM sensor (CDM_C and CDM_T, respectively) and to the data obtained by the test bench during the experiments (PC and FC-DLC). This nomenclature is followed by the test date and operating conditions: the operating pressure 0.5 bar , the operating temperature 65ºC, the anode stoichiometry λa=1.3, the anode relative humidity RHa=60%, the cathode stoichiometry λc=2.5 and the cathode relative humidity RHc=60%.
