Abstract: A method for manufacturing a unit cell for a fuel cell includes preparing a separator having a reaction area located to correspond to an anode or a cathode of the unit cell, a first protrusion protruding from the separator, and a second protrusion spaced apart from the first protrusion with the reaction area interposed therebetween. The method includes providing a passage configured to guide a reaction gas to flow in the reaction area, and arranging a porous passage having a height protruding to become farther away from the separator and to be higher than the first and second protrusions between the first and second protrusions in parallel. The method includes compressing the porous passage toward the separator. The porous passage is fixed to the separator via the first and second protrusions by a force applied between the porous passage and the protrusion as the passage is deformed or is apt to be deformed to be lengthened in a transverse direction due to the compression of the porous passage.

Abstract: A fuel cell includes an electrolyte membrane, first and second electrode layers disposed on first and second surfaces of the electrolyte membrane, respectively, the second surface being opposite to the first surface. One of the first and second electrode layers is an anode electrode layer and the other is a cathode electrode layer. Additionally, first and second gaskets are disposed on the first and second surfaces of the electrolyte membrane, respectively, to be adjacent to an edge of the electrolyte membrane. The first electrode layer includes a first main electrode layer disposed on the first surface of the electrolyte membrane and inside the first gasket and a first sub-electrode layer having a first portion inserted between the first main electrode layer and the electrolyte membrane and a second portion inserted between the first gasket and the electrolyte membrane.

Abstract: A unit cell for a fuel cell includes a separator having a reaction area located to correspond to an anode or a cathode of a membrane electrode assembly, an inlet manifold, which is provided outside the reaction area and into which a reaction gas is introduced that is to be supplied to the reaction area, and an outlet manifold which is spaced apart from the inlet manifold and through which the reaction gas that passed through the reaction area is discharged. The unit cell has a porous passage provided between the separator and the membrane electrode assembly arranged to be adjacent to the separator and having a passage configured to guide the reaction gas introduced into the inlet manifold such that the reaction gas is discharged to the outlet manifold via the reaction area. The unit cell has a protrusion protruding from the separator toward the porous passage, which is fixed to the separator by the protrusion through a pressing force, which is generated due to deformation by a compressive force.

Abstract: An electronic pedal device obtains a reliable and stable operation without generating noise by using a mechanism that converts a pivot of a treadle about a pedal body into a pivot of a link and then transmits the pivot of the link to a sensor. The device includes a base plate, pedal body, treadle, resilient member, sensor, and link.
