Abstract: A fuel cell system having a direct liquid fuel cell that uses a liquid containing a formic acid or an alcohol as a fuel includes: a fuel tank that stores the fuel to be supplied to the fuel cell; a fuel supply device that supplies the fuel in the fuel tank to the fuel cell; and a bubbling device that blows an inert gas into the fuel stored in the fuel tank.

Abstract: A fuel cell system includes a fuel cell, an electric power recovery device, and a control device that controls the fuel cell and the electric power recovery device. In a state where supplying of the liquid fuel to the fuel cell is stopped, the control device charges post-stop electric power generated by the fuel cell using the liquid fuel that has been already supplied, thereby recovering the post-stop electric power into the electric power recovery device, and thereafter stopping an electrode reaction in an electrode structure of the fuel cell.

Abstract: A fuel cell includes a discharge structure that discharges water generated in a cathode electrode in association with an electrode reaction in the MEA to the outside. The discharge structure includes a discharge path through which air that is an oxidant flows, a passage that communicably connects an oxidant supply flow path and the discharge path and that moves water generated in the cathode electrode to the discharge path, and a discharge portion that discharges the generated water moved to the discharge path to the outside.

Abstract: A gate pad is disposed on a semiconductor layer composed of an n+ type substrate, an n− type epitaxial layer, and a p− type body layer. The gate pad is disposed at the center portion of the semiconductor layer as viewed in plan. A plurality of unit cells that compose a trench type MOSFET element are provided in the semiconductor layer. The plurality of unit cells are arranged in the radial direction about the gate pad as viewed in plan. A gate electrode of a unit cell (center-side unit cell) that is proximate to the gate pad is electrically connected to the gate pad. Gate electrodes of unit cells that are adjacent to each other in the radial direction are connected to each other.
