Abstract:
Disclosed is an electrolyte membrane which enables a fuel cell to have a high maximum output when used therein since it has high proton conductivity and high hydrogen gas impermeability. Also disclosed are a method for producing such an electrolyte membrane, and a solid polymer fuel cell using such an electrolyte membrane. A method for producing an electrolyte membrane including a step for impregnating a porous base with a solution containing a sulfonic acid group-containing vinyl monomer and then polymerizing the monomer is characterized in that 80% by mole or more of vinyl sulfonic acid having purity of 90% or more, and/or a salt thereof is contained as the sulfonic acid group-containing vinyl monomer, and the concentration of the vinyl sulfonic acid and/or a salt thereof in the solution is set at 35% by weight or more.
Abstract:
An image display controlling unit controls to display a standard image and a dummy image. The standard image is an image that has been previously decided by the user. The dummy image looks like the standard image but the standard image and the dummy image has differences that only the user can identify and that can not be identified from a distance. The user selects a predetermined section of the standard image and selects a dummy section from the dummy image. A password is input based on information corresponding to the predetermined section of the standard image and information corresponding to the dummy section of the dummy image is neglected.
