摘要:
The administration efficiency of a drug may be improved by establishing compatibility between the suppression of the release of a biological counter ion from a living body's biological interface and the maintenance of a good state of contact between each of a working electrode structure and a nonworking electrode structure and the biological interface. Coating films each composed of an external preparation containing: a hydrophilic polymer matrix agent; and an ion-exchange resin dispersed in the hydrophilic polymer matrix agent, or coating films each composed of an external preparation containing a hydrophilic polymer having an ion-exchange function are formed on the biological interface, and iontophoresis is performed through the coating films.

A single cell comprising a fuel electrode, an air electrode, and an electrolytic layer or hollow layer interposed between those electrodes, or a fuel cell comprised of a stack of these single cells, wherein a supply port is formed on the fuel electrode side for supplying a hydrogen-based/oxygen-based mixed gas obtained by electrolyzing an electrolyte fluid by agitating and stirring and collecting the resulting gas; moreover the fuel electrode to which the hydrogen-based/oxygen-based mixed gas is supplied is gas-permeable. The hydrogen-based/oxygen-based mixed gas contains H, H2, H3, and/or HD, OH, 16O, and O2.
