摘要:
A fuel cell device is provided that may remove water that has been generated on the surface of a cathode. When the display member of a mobile phone is opened, a shutter member slides from a protection position to an open position. A water absorbing block is thereby moved toward a protrusion portion while contacting the surface of a cathode of a fuel cell, absorbing and removing water that has accumulated on the surface of the cathode. The water absorbing block is moved along the surface of the cathode by simply opening and closing the mobile phone in this manner, and the water that has been generated on the surface of the cathode may be absorbed and removed.

A fuel cell includes membrane electrode assemblies disposed in a planar arrangement. Each membrane electrode assembly includes an electrolyte membrane, an anode catalyst layer, and a cathode catalyst layer disposed counter to the cathode catalyst via the electrolyte membrane. Interconnectors (conductive members) are provided on the lateral faces of the electrolyte membranes disposed counter to each another in the neighboring direction of the membrane electrode assemblies. Each interconnector includes a support portion protruding toward the central region of the electrolyte member on the cathode side of the electrolyte membrane. The support portion is in contact with the cathode-side surface of an edge of the electrolyte membrane, and the electrolyte membrane is held by the support portion.

A base as a support in a fuel cell is provided with a plurality of through holes. An electrolyte membrane covers the entirety of the base facing the anode and is partly embedded in the plurality of through holes. A cathode is embedded in the through holes such that each block is in an isolated area bounded by the base and the electrolyte membrane. A current collector is provided on the blocks of the cathode and on the base partitioning the cathode. The current collector is secured to the base by a securing member.
