A power converter includes a capacitor and a substrate on which a plurality of switching elements for power conversion are mounted. The power converter includes a cooler for cooling the plurality of switching elements and a housing that accommodates the capacitor, the substrate, and the cooler. The power converter includes a power connector exposed from the housing and an output connector exposed from the housing. The power converter includes a plurality of lines that include a plurality of power lines each electrically connected to the capacitor, given switching elements, and the power connector. The plurality of lines include a plurality of output lines each electrically connected to given switching elements and the output connector. At least one among the plurality of lines is a line that includes a conductive pattern formed on the substrate.

Power converter

A power converter includes a positive busbar electrically connected to a positive terminal and the first capacitor electrode, and includes a negative busbar electrically connected to a negative terminal and the second capacitor electrode. The power converter includes output busbars each electrically connected to a given output terminal among multiple output terminals, a given high-side switching element among a plurality of high-side switching elements, and a given low-side switching element among a plurality of low-side switching elements. The power converter includes a cooler that cools the high-side switching elements and the low-side switching elements. The power converter includes a housing that accommodates a supply tube and a discharge tube. The positive terminal, the negative terminal, the output terminals, the inlet port, and the outlet port are exposed on the housing. The inlet port, the outlet port, the supply tube, and the discharge tube are separate members from the housing.

A positive electrode catalyst, for use in a positive electrode in a device provided with the positive electrode and a negative electrode, in which a reaction represented by 4OH&#x2192;O+2HO+4eis performed on a side of the positive electrode. The positive electrode catalyst includes a layered metal oxide, wherein the layered metal oxide is a Ruddlesden-Popper type layered perovskite represented by (LaA) (FeB)(SrC)Owherein, A is a rare earth element other than La, B is a transition metal other than Fe, and C is an alkaline earth metal other than Sr; and x satisfies an expression: 0&#x2266;x&#x3c;1, y satisfies an expression: 0&#x2266;y&#x3c;1, z satisfies an expression: 0&#x2266;z&#x3c;1, and a satisfies an expression: 0&#x2266;a&#x2266;3.
