The fuel cell is the energy source that can commercialize, and it can solve the problem of the fossil fuel; such as the limitation of deposit production, the production of the environmental pollution material. The components of the fuel cell needs the high quality of reliability because this fuel cell circulates the explosive work fluid. For this purpose, the evaluation method of the components is necessary to secure the reliability in the fuel cell. However, there have no global standard for the components in the fuel cell or local one. This study concerns about the evaluation method of the durability test. At the first, the substitution preventing valve is selected to confirm the reliability with a durability test. And the evaluation method is set up from the standard of the general purpose solenoid valve. At the final, the reliability of the repetitive operation is verified from the test results of a durability test.

Usually, the detailed information for design the optimal solenoid valve is needed for supporting the high level valve to consumers. Also, some valves which are used for nuclear power plant cannot define the design parameters because there is no precise information about the object valve. Therefore, the designer tries to find the information from the inverse design data that was derived from the analysis of conventional valve or experimental results of one. In this paper, inverse design strategy for designing the Q-class solenoid valve for nuclear power plant is studied, and experimental setup is also suggested and manufactured. The flow rate of the valve for designing the valve open area and displacement is calculated, and the pressure characteristics of the valve for designing the attraction force are experimented and discussed.

This study have goal with conceptual design for offshore Structures of high pressure drop control valve for localization. Numerical simulation using CFD(Computational Fluid Dynamic) in order to predict a mass flow rate and a flow coefficient form flow dynamic point of view. The working fluid assumed the glycerin(C3H8O3). Relation with flow and flow coefficient can not be proportional according to inlet pressure when compare with mass flow rate. Because flow coefficient have influence in flow and pressure difference. The structural analysis used ANSYS which is a commercial code. Stress analysis result of internal pressure in valve showed lower than yield strength. This is expect to need more detail design and verification for stem and seat structure.
