Abstract: A load sensor includes: a first base member and a second base member disposed so as to face each other; an electrically-conductive elastic body disposed on an opposing face of the first base member; a wire member that is electrically conductive and disposed between the second base member and the electrically-conductive elastic body; and a dielectric body disposed between the electrically-conductive elastic body and the wire member. A permittivity of the dielectric body is changed in a contact surface direction in which contact of the dielectric body advances in association with increase in a load, such that a form of change in capacitance between the electrically-conductive elastic body and the wire member associated with change in the load becomes close to that of a straight line.

Abstract: Disclosed is a catalyst layer for a fuel cell that has good gas diffusion properties in the entire catalyst layer and in which coarsening of catalyst particles can be suppressed. The catalyst layer for a fuel cell includes fibrous conductive members and catalyst particles. The fibrous conductive members are inclined relative to the surface direction of the catalyst layer, and the length L of the fibrous conductive members and the thickness T of the catalyst layer satisfy the relational expression: L/T≤3. Each of the catalyst particles includes a core portion and a shell portion that covers the core portion, and contains a component different from that of the core portion.

Abstract: An electrolytic capacitor includes a capacitor element including a porous anode body, an anode wire partially embedded in the anode body, a dielectric layer formed on a surface of the anode body, and a solid electrolyte layer covering at least a portion of the dielectric layer, wherein the anode body is formed of a first metal, the anode wire is formed of a second metal having a different composition from the first metal, and the second metal has a conductivity S2 that is larger than a conductivity S1 of the first metal. This allows for providing an electrolytic capacitor which suppresses an increase in production costs and has a low ESR.

Abstract: A membrane electrode assembly includes an electrolyte membrane, and a pair of electrodes sandwiching the electrolyte membrane. The pair of electrodes each include a catalyst layer, and a gas diffusion layer disposed on the catalyst layer on an opposite side to the electrolyte membrane. At least one of the catalyst layers contains first catalyst particles, and second catalyst particles. The first catalyst particles are either platinum particles or platinum alloy particles, or both. The second catalyst particles are core-shell particles having a core part and a shell part, the core part formed of at least one selected from transition metals other than platinum, the shell part covering the core part and formed of at least one of platinum and a platinum alloy. In the catalyst layer, the second catalyst particles are present in a smaller percentage in an electrolyte membrane side than they are in a gas diffusion layer side.
