The storage control device of the present invention is able to perform input and output of data between blocks whose size is different with good efficiency. Conductive particles are provided in the nip and a time factor represented by a following equation satisfies a condition 15:. In operation, water vapor permeates through the membrane and passes on through the connecting elements to humidify the gas being supplied to the fuel cell. The tool can be made disposable by the use of injection molded plastic materials.
