MANUFACTURING METHOD OF POLYELECTROLYTE MEMBRANE ACTUATOR AND POLYELECTROLYTE MEMBRANE ACTUATOR

摘要

PROBLEM TO BE SOLVED: To improve the evenness of a thickness of a metal electrode, and to improve safety so as to prevent a fire from occurring due to a short circuit and overheat, in a polyelectrolyte membrane actuator dynamically driven by being applied with a voltage.;SOLUTION: This polyelectrolyte membrane actuator 10 comprises an actuator layer 12 which is formed of polyelectrolyte membranes impregnated with electrolyte solutions, and electrodes 15, 17 which are arranged in the actuator layer 12 along both faces of the actuator layer. The actuator layer 12 comprises outer layers 14, 16 which are formed at both sides of the actuator layer 12, and formed of the first polyelectrolyte membranes, and an inner layer 18 which is composed of a membrane material containing a layer which is low in ion exchange capability with respect to the first polyelectrolyte membranes, and interposed between the outer layers 14, 16.;COPYRIGHT: (C)2008,JPO&INPIT
