Provided is a Si—Ge laminated thin film including at least one Si layer and at least one Ge layer, which are alternately laminated on a substrate (1). A Si layer (31) and a Ge layer (22) each have a thickness in a range of 5 to 500 nm. The Si layer (31) is amorphous and only the Ge layer (22) is crystallized. An average crystallite size of Ge in the Ge layer (22) is 20 nm or less.

Electric power is supplied from a fuel cell to a portable personal computer (210) having a heat-producing section (212) which generates heat during operation. The fuel cell includes electrolyte, a fuel electrode and an oxidant electrode arranged to sandwich the electrolyte, and a fuel supply section capable of supplying fuel which has absorbed heat of the heat-producing section (212) to the fuel electrode. The fuel supply section removes the heat from the heat-producing section (212) by supplying fuel to the fuel electrode when the fuel is heated by heat exchange. Thus, it is possible to improve the battery efficiency of the fuel cell and suppress increase of the temperature of the heat-producing section.

A fuel cell system includes a fuel cell main body which has a solid polymer electrolytic membrane, a fuel electrode and an oxidant electrode attached to the solid electrolyte membrane; a fuel storage unit which stores liquid fuel; a polymer membrane having a proton conductivity and provided in the fuel storage unit; a concentration detection unit (a first electrode terminal and a second electrode terminal) which detects the alcohol concentration of the liquid fuel in the fuel storage unit based on the alteration of the proton conductivity of said polymer membrane; and a concentration measurement unit.
摘要:
A plurality of fuel electrodes are disposed on one surface of a solid polyelectrolyte membrane, while a plurality of oxidizer electrodes are disposed on the other surface of the same to create a plurality of unit cells which share the solid polyelectrolyte membrane. These unit cells are electrically connected through connection electrode extending through the solid polyelectrolyte membrane. A groove is formed in a region of the solid polyelectrolyte membrane between adjacent unit cells. This groove limits the migration of hydrogen ions to adjacent unit cells to prevent a reduction in voltage. The resulting solid polymer fuel cell, which is in a simple structure and reduced in size, can provide high power.
