| Abstract | ||||
| Alkaline water electrolysis is the most practical method for producing large amounts of hydrogen using renewable energy sources. However, water electrolyzers perform poorly at low load conditions, thereby restricting their operational capacity. Power loss due to current is the main reason for poor efficiency under low loads. The article explains the inefficiency and proposes an improved water transformer model based on the electrolyzer's internal construction. PWM electrolysis significantly enhances hydrogen generation efficiency at low loads compared to cells supplied with direct current. This study examines the effects of duty ratio and pulse width modulation (PWM) on efficiency enhancement. It is feasible to regulate them under different operating conditions. You may also change the efficiency trend by adjusting the electrolyzer's parameters. Finally, employing pulse width modulation (PWM) for electrolysis to generate hydroxyl gas helps maintain lower cell temperatures and enhances productivity compared to a system linked to direct current. . . | ||||
