Abstract: A sheet frame module capable of forming an airtight line and flow path of reaction gas by bonding a plurality of sheet frames configured in a flat shape separately from a separator, and a unit cell for a fuel cell including the same, is disposed between a pair of separators for a fuel cell to form an airtight line and flow path of reaction gas, and includes a center sheet frame in which a membrane electrode assembly is disposed at a center portion thereof; a first side sheet frame disposed between one side of the center sheet frame and one of the pair of separators to form an airtight line and flow path of a first reaction gas; and a second side sheet frame disposed between the other side of the center sheet frame and another of the pair of separators to form an airtight line and flow path of a second reaction gas.

Abstract: A mobile station comprises a substrate having circuitry adapted to perform communication functions. The mobile station also comprises a keypad adapted to receive input from a user to control the mobile station, wherein at least one key of the keypad is operably coupled to the substrate. The mobile station also comprises an antenna at least partially housed in the at least one key to receive wireless communications. The wireless communications may comprise satellite communications, such as digital multimedia communications. The keypad may comprise input keys adapted to receive input of numbers and characters, and the a multi-key having a plurality of radially arranged buttons. The keypad may also comprise function keys arranged around the multi-key, and a padbase adapted to fix the input keys, the multi-key, and the function keys on the surface of the keypad. The antenna may be positioned in a lower portion of the multi-key.
