摘要:
A mobile device includes a housing in which an opening is defined, a lid freely uncovering or covering the opening. The lid has a body plate that defines part of the outer shape of the mobile device. The lid has a fitting projection projecting from the opening side face of the body plate and fitting into the opening. The lid has a groove formed all the way along a periphery so that a waterproof O-ring is disposed. The O-ring prevents entry of water into the opening by being fitted in the groove so as to be in contact with an internal wall face of the opening. The projection has a plurality of pressing ribs that are separately disposed along the groove so as to project in the inward direction of the groove at least in a portion opposite the rotation shaft and so as to narrow the groove.

A mobile terminal apparatus includes a light source that emits light and a housing. The housing has: a box section with an opening section and the light source fitted in the opening; and a panel that is fitted to the box section and that covers a front of the light source. The panel also has a light diffusion transmission layer for diffusing and transmitting light, which is disposed on a surface of the panel facing the light source.

A membrane-electrode assembly for a direct oxidation fuel cell includes an electrolyte membrane, and an anode and a cathode sandwiching said electrolyte membrane. The cathode includes a catalyst layer in contact with the electrolyte membrane and a diffusion layer formed on the catalyst layer, and the catalyst layer contains 2 to 20% by volume of pores. A direct oxidation fuel cell including this membrane-electrode assembly has excellent power generating performance and durability.

A direct oxidation fuel cell includes at least one cell. The cell includes a membrane electrode assembly including an anode, a cathode, and an electrolyte membrane disposed between the anode and the cathode. The cell also includes: an anode-side separator being in contact with the anode and having a fuel flow channel for supplying a fuel to the anode; and a cathode-side separator being in contact with the cathode and having an oxidant flow channel for supplying an oxidant to the cathode. The electrolyte membrane includes an ion exchange resin and has an ion exchange capacity per unit volume which is smaller upstream of the fuel flow channel than downstream thereof.

A fuel cell system includes a fuel cell stack for generating power and power generation control means. The fuel cell stack has at least one cell that includes a cathode to which an oxidant is supplied, an anode to which a fuel is supplied, and a polymer electrolyte membrane sandwiched between the cathode and the anode. The power generation control means has dryness degree determination means for determining the degree of dryness of the fuel cell stack based on shut-down period. When the shut-down period is shorter than a predetermined period of time, the power generation control means supplies a gas for drying to the cathode for a predetermined period of time, to remove water remaining in the cathode. When the shut-down period is equal to or longer than the predetermined period of time, such a drying operation is not performed.
