Abstract: A hydrogen system includes: a compressor in which protons extracted from an anode fluid supplied to an anode move to a cathode through an electrolyte membrane and compressed hydrogen is generated; and a first eliminator including: a water-permeable membrane; a cathode gas flow path through which a cathode gas discharged from the cathode of the compressor flows, the cathode gas flow path being provided on one main surface of the water-permeable membrane; and an accommodation portion provided on the other main surface of the water-permeable membrane and filled with a liquid at a pressure lower than that of the cathode gas. The first eliminator removes moisture contained in the cathode gas.

Abstract: The parameter determination method according to the present disclosure is a parameter determination method for determining a value of a parameter that is used for a simulation of determining gas transportability in a space inside a pore and that defines a boundary condition at an interface between a wall surface and gas or ions inside the pore, the method including determining the value of a parameter that reproduces a first concentration ratio indicating a ratio of the gas or ion concentration inside the pore to the gas or ion concentration outside the pore as the value of the parameter that defines the boundary condition.

Abstract: A gas diffusion simulation method for simulating diffusion of a gas in a porous material having many pores, the method includes: calculating, in the pores, a Knudsen diffusion coefficient based on the mean square displacement of first gas particles in spaces surrounded by wall surfaces and a Knudsen diffusion term using the Knudsen diffusion coefficient, calculating an interdiffusion term using an interdiffusion coefficient between the first gas particles and second gas particles different therefrom, and performing simulation of the gas diffusion of the first gas particles by using a diffusion equation of the first gas particles represented by the sum of the Knudsen diffusion term and the interdiffusion term.
