A Novel Evaluation Method of Powder Electrocatalyst for Gas Evolution Reaction

<p>The evaluation of the powder catalyst activity is essential for the development of high-performance electrocatalysts for water electrolysis. However, the gas generated therein interferes with the accurate measurement by covering the catalyst surface. In this study, we have developed a new evaluation method for a powder oxide electrocatalyst using an alkaline electrolyte. This measurement and analysis method can obtain the intrinsic catalyst activity with no influence from the generation of bubbles. To establish this method, the electrolyzer for evaluation adopts the interdigit flow field for the <i>forced-flow method</i>, and the two methods, namely <i>time zero analysis</i> and <i>flow rate infinitization analysis</i>, were demonstrated by the extrapolation of the measurement data. As a result, the combination of <i>forced-flow method</i> and <i>time-zero analysis</i> is the best evaluation method for the determination of kinetic current at time zero as the equivalent of the no-generation gas condition.</p>
Heat and Mass Balance Analysis of 130-W Active-type Direct-methanol Fuel Cell

<p>A “heat- and mass-balance analysis” for a direct-methanol fuel cell (DMFC) system, accounting for actual experimental data and the heat- and mass transfer of the DMFC, is proposed to facilitate the usage of general spreadsheet software. The spreadsheet software enables the use of various functions on the data and visualizes the data using graphs. In addition, this application has a light computational load and is thus easy to implement in system control. The output of the analysis is the transfer of material and heat within the DMFC, as well as the heat balance and electrical efficiency of the DMFC. The analysis was verified using experimental data of the DMFC system, and the results of the verification indicated that the analysis could predict heat balance and system efficiency with accuracies of approximately 3.7 and 2.5 %, respectively. Further, the analysis was used to investigate the effect of stack temperature on the electrical efficiency of the system, and the results showed that the optimum stack temperature at a system power of 130 W was 60 °C and the electrical efficiency at that temperature was 21.8 % HHV.</p>

<p>In this study, we propose a highly accurate catalyst evaluation method by improving the time-zero analysis, which has been reported as an activity evaluation method for gas evolution powder catalysts. We refined the extrapolation approach to plot in this study’s time-zero analysis as an analytical method. The Tafel slopes obtained with this method for LaNiO<sub>3</sub> (LNO) were found to be within the reported range, and the data was consistent in catalytic loading range of 2.5–3.3 mg<sub>-LNO</sub> cm<sup>−2</sup>. Using the improved time-zero analysis, the kinetic activity of the gas evolution powder catalyst is possible to be evaluated with high accuracy.</p>
