Abstract: A fuel tank for a fuel cell includes a fuel valve which allows a methanol water solution to pass to a fuel supply portion from a fuel injecting portion after joining a fuel cell main body and the fuel tank for the fuel cell, and shuts off the passage of the methanol water solution before the fuel supply portion and the fuel injecting portion are disconnected. Accordingly, the fuel valve is properly opened and closed, the liquid fuel does not leak out from the fuel tank for the fuel cell at a time of attaching and detaching, and it is possible to improve a safety in the fuel supply in comparison with the conventional structure.

Abstract: A first variable resistor (5) is connected between a first terminal (7) and a third terminal (9) and increases/reduces its resistance value in accordance with the polarity of a pulse voltage applied between the first terminal (7) and the third terminal (9). A second variable resistor (6) is connected between the third terminal (9) and a second terminal (8) and increases/reduces its resistance value in accordance with the polarity of a pulse voltage applied between the third terminal (9) and the second terminal (8). Given pulse voltages are applied between the first terminal (7) and the third terminal (9) and between the third terminal (9) and the second terminal (8) to reversibly change the resistance values of the first and second variable resistors (5, 6), thereby recording one bit or multiple bits of information.
