摘要： 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.

摘要： An electrochemical device (100) includes an ion exchange membrane (120), a first electrode (110) adjacent to a first side thereof and a second electrode (130) adjacent to a second side thereof. At least one of the first electrode (110) and the second electrode (130) includes a current collector layer (112, 132) and a catalyzing layer (114, 134) applied thereto. The catalyzing layer (114, 134) includes an ion-conducting polymer (116), a plurality of electroactive catalyst particles (115, 118) and an adhesive (118) that binds the polymer (116), the catalyst particles (115, 118) and the current collector layer together (112, 132). In a method of making an electrode, an ion-conducting polymer, a plurality of electroactive catalyst particles and an adhesive are mixed in a solvent, which is applied to a current collector layer. The solvent is evaporated so that the adhesive binds the polymer and the catalyst particles to the current collector.

摘要： Disclosed are: a polymer electrolyte membrane which can prevent ionic conductor loss even upon the occurrence of chemical degradation in the ionic conductor according to long term use and thus can be significantly improved in chemical durability; a manufacturing method therefor; and an electrochemical device comprising same. The polymer electrolyte membrane of the present disclosure comprises a polymer electrolyte material. The polymer electrolyte material comprises an ionic conductor and a crosslinker unbound to the ionic conductor. The crosslinker has at least one cross-linkable functional group which can couple with the ionic conductor that has been degraded, thereby causing crosslinking with the ionic conductor.
