Lab Scale Production of Wind Power-Fuel Cell Hybrid Systems by Use of Electrolysis Process and Study of Technical Analysis

The wind is one of developing sources of renewable energy in recent years. Wind power often is unusable at peak times. Therefore¡ a storage system or backup power is always necessary. In this study¡ a hybrid system was applied for a wind turbine to provide the reliable power. The hybrid system consisted of four main components: a wind turbine¡ electrolyzer¡ hydrogen storage and fuel cell. The extra electricity produced in fewer demand hours by wind turbine was conducted to a hydrogen and oxygen generator system. Hydrogen were stored in a tank. Then¡ hydrogen was introduced to a fuel cell unit in order to produce electricity at peak times (when the electricity produced by wind power was less than demand). The hydrogen production rate by alkaline electrolysis as well as the electricity production by PEM fuel cell was investigated. The maximum hydrogen produced by the system per hour average was 304 ml and the power produced by the fuel cell was 1008 mW. After the construction of the prototype¡ a case study for this system was done in Kouhin area.
