The objective of this study is to produce maximum hydrogen from advanced alkaline electrolyzer. The input electricity of electrolyzer is generated with wind turbine. The wind turbine is utilized with a self-exited induction generator. The effect of variation of temperature in electrolyzer is investigated, considering both thermal and electrochemical equations of electrolyzer. The optimal sizing of wind turbine is performed to maximize the hydrogen production and minimize the excess power. Actual data for weekly wind speed of Sahand, Iran, is used. Results show that for a 10 kW electrolyzer, the optimized nominal power of wind turbine is 11 kW at wind speed of 12 m/s. The hydrogen production and average excess power during weekly performance of system are 8297 mol and 0.19 kW, respectively.
