Modeling of thermal performance of a commercial alkaline electrolyzer supplied with various electrical currents

Hydrogen produced by solar and other clean energy sources is an essential alternative to fossil fuels. In this stuy, a commercial alkaline electrolyzer with different cell numbers and electrode areas are simulated for different pressure, temperature, thermal resistance, and electrical current. This...
