The small wind turbines has the merits of setting up with low costs by individuals, and get the energy saving effects that, it has the secured, separate markets from the big range systems, and the developing of it is continuously proceeding. The objective of this paper is to provide the design characteristics analysis of a permanent magnet synchronous generator(PMSG) skewed for magnet of rotor, the main advantage to be explored with the use of a split core design is the reduction in manufacturing costs and its simplicity in manufacture, compared to the manufacturing costs of a core skew PM machine. This thesis is aiming mainly analyzing the characteristics of the prototype to verify through Finite Element Method(FEM) and tests.

Fuel cell system is being connected with electric power system, because this system has high energy conversion efficiency, siting flexibility and good environment reservation effect. Fuel cell system requires balanced current density and temperature distribution on the stack for getting system stability. Imbalance of current density and temperature distribution makes the output efficiency of the cell worse and life time short. Current density distribution on the cell plate depends on the partial pressures of the reaction gases. Temperature distribution on the cell plate depends on the heat energy generation caused by activation energy for reaction and internal resistance of the cell plate. Therefore this paper presents the effects of cell operating voltage, current density and temperature distribution on the unit cell and stack about cross flow of phosphoric acid fuel cell system.
