Integration Design of Wind Energy - Hydrogen

Fuel Cell

Abstract Wind energy is a new renewable energy. But there are some problems for energy storage and energy grid. Hydrogen fuel cell has the characteristics of environment friendly, high efficiency, low noise. And also is a very good energy storage method. In recent years, integrating the hydrogen fuel cell and wind turbines is popular in new energy researching and extension field.The principle of hydrogen fuel cell and wind turbines have discussed in this article. The hydrogen fuel cell and wind turbines have been integrated. An electrolyzer and a hydrogen storage system have been added. The integrating of wind and hydrogen fuel cell can achieve maximum utilization value. The system parameters have been designed for operation. The system optimization measures were discussed. The designed system has a long life, ease maintenance, simple operation. This study is of significance for the further application of wind energy and the construction of new energy

Key words: hydrogen fuel cell; wind energy; design; integration
