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.

Fuel cell system

A gate pad and a source pad are disposed on a semiconductor layer. The gate pad is disposed at the center portion of the semiconductor layer and has the shape of a circle centered on the center of the semiconductor layer as viewed in plan. The source pad is disposed so as to surround the gate pad, and has the shape of a circular ring centered on the center of the semiconductor layer as viewed in plan. A plurality of unit cells that compose a trench type MOSFET element are formed in the semiconductor layer.

Semiconductor device for reducing gate wiring length

A gate pad is disposed on a semiconductor layer composed of an ntype substrate, an ntype epitaxial layer, and a ptype 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.
