Abstract: An electrode catalyst layer of an electrochemical device is an electrode catalyst layer of an electrochemical device, the electrode catalyst layer including a mesoporous carbon; a catalyst metal supported at least in the mesoporous carbon; and an ionomer. Before supporting the catalyst metal, the mesoporous carbon has mesopores with a mode radius of 1 nm to 25 nm and a pore volume of 1.0 cm3/g to 3.0 cm3/g and has an average particle diameter of 200 nm or more.

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: An apparatus includes a proton-conducting electrolyte membrane, an anode, a cathode, a first flow path which is disposed on the anode and through which an anode fluid containing hydrogen as a constituent element flows, a second flow path which is disposed on the cathode and through which hydrogen flows, a voltage applicator, a detector which detects a hydrogen cross leak amount passing through the membrane, where the detector detects the hydrogen cross leak amount from, a natural potential of one electrode of the cathode and the anode after forming a state where hydrogen is present at the one electrode and hydrogen is not present at the other electrode of the cathode and the anode, or a current flowing between the anode and the cathode when the voltage is applied from the voltage applicator in a state where the first flow path and the second flow path are both sealed off.
