Battery and seal unit

According to one embodiment, a fuel cell includes an electric-power generator, a fuel distribution mechanism, and a pump. The electric-power generator includes a membrane electrode assembly including an anode, a cathode, and an electrolytic membrane. The fuel distribution mechanism includes a container and a thin tube. The container includes a fuel discharge surface, and contains the electric-power generator inside. The thin tube is formed in the container in a manner that a fuel outlet and a fuel inlet communicate with each other. The pump is connected directly to the fuel inlet.

Fuel cell

Coupler for transferring a liquid or other material between containers

The present invention relates to a fuel cell including: a membrane electrode assembly () having a fuel electrode (), an air electrode (), and an electrolyte membrane () sandwiched therebetween; and a fuel storage unit () storing a liquid fuel. The fuel cell is capable of continuously generating electricity for long hours only by being replenished with a fuel, and therefore, attempts have been made to miniaturize the fuel cell to use it as a power source of portable electronic devices. When the membrane electrode assembly and the fuel storage unit in the fuel cell are connected via a flow path, a fuel supply state becomes uneven depending on the shape and the like of the flow path even though a supply amount of the fuel can be adjusted, which causes a problem such as a decrease in an output of the fuel cell. The present invention solves the aforethe problem by providing, in the fuel cell, a fuel distributing mechanism () which supplies the fuel to a plurality of places of the fuel electrode, and connecting the fuel distributing mechanism and the fuel storage unit via the flow path ().

In electronic equipment using a fuel cell as a power source, an antenna and a fuel cell, which are provided in a lower case of a main body receiving electronic parts, are arranged at a given distance from each other. An acceptable communication state can be established in the electronic equipment.

Nonaqueous electrolyte secondary battery

A bone mineral content measuring apparatus for obtaining the bone mineral content of an object to be examined by irradiating X-rays onto the object and measuring the X-rays which have passed through the object. An X-ray generating device generates X-rays having a continuous spectrum. The X-rays generated pass through an X-ray filter before the irradiation of the object or after the transmission of the object. The X-ray filter is composed of a substance having an X-ray absorbing characteristic with the K-absorption edge at a predetermined energy value. The X-rays which have passed through the X-ray filter and the object are detected by the X-ray detector. A data analyzer inputs the detected X-ray detection data and analyzes the bone mineral content of the object on the basis of the X-ray absorbing characteristic of the X-ray filter.
