Description

<p>In recent years, hydrogen energy with less environmental load has been attracting attention, and fuel cells play a fundamental role. Among them, polymer electrolyte fuel cells (PEFCs) are used in various applications because of their high power density, compact size, and light weight. However, the output of fuel cells declines due to various factors. For stable operation, it is important to control the fuel cells by measuring or calculating their characteristics. In this study, to establish the overpotential evaluation method for fuel cell operation control, we evaluated it by a method that combines detection of series resistance components by frequency application and a overpotential separation method.</p>
