Abstract: A catalyst for an oxygen reduction reaction containing catalyst particles having a shell-core structure containing a PtCo alloy or a PtCoMn alloy as a core, and platinum as a shell layer. A specific plane of a face-centered cubic lattice is formed by a plurality of platinum atoms contained in the shell layer, and a lattice constant of the plane of the face-centered cubic lattice on the catalyst particle surface is 3.70 Å or more and 4.05 Å or less (in a PtCo alloy), or 3.870 Å or more and 4.10 Å or less (in a PtCoMn alloy). A catalyst design method includes a step of calculating, with respect to an orientation plane such as the plane formed by platinum atoms of the shell layer, adsorption energies for an oxygen molecule, an OH group and a water molecule by first-principles calculation based on density functional theory.

Abstract: Provided is a temperature calibration method that makes it possible to efficiently calibrate temperature in a short time and enhance temperature calibration accuracy. This temperature calibration method uses a temperature calibration device (10) comprising a temperature calibration block (2) having formed therein a placement part (25) for a reference temperature sensor (5) and a temperature sensor (T) to be calibrated. In this temperature calibration method, a temperature state in a gradual temperature variation transition process of the temperature calibration block (2) is taken to be a calibration temperature. The temperature calibration device (10) comprises: a vacuum-insulated container (1) comprising a vacuum region (Va) surrounding the temperature calibration block (2) and an accommodation part for accommodating the temperature calibration block (2); and a Peltier module (3) that is thermally coupled to the temperature calibration block (2).
