NOVELTY - A flow channel plate (200), adapted to a fuel cell apparatus (300), comprises a separating film (210), disposed between two modules (310) of the fuel cell apparatus; and several bar supporting members (220), leaning against the separating film and the components for maintaining a distance between the components.    USE - As a flow channel plate for fuel cell apparatus useful as power source.    ADVANTAGE - The flow channel plate has low flow resistance. Compared to the conventional flow channel plate fabricated through plastic injection molding, the separating film of the flow channel plate is thinner, and the thickness of the separating film is be lower than 0.25 mm. Thus, the gas flowing space in the flow channel plate is larger, and accordingly the resistance to the reactive gas is smaller, therefore a smaller fan with lower power is used for supplying the gas required by the cathodic reaction into the flow channel plate. Accordingly, the volume of the fuel cell apparatus is reduced and the output power is improved. The supporting members prevent the flow channel plate from being damaged by the compressing pressure.    DETAILED DESCRIPTION - A flow channel plate (200), adapted to a fuel cell apparatus (300), comprises a separating film (210), disposed between two components/modules (310) of the fuel cell apparatus; and several bar supporting members (220), leaning against the separating film and the components for maintaining a distance between the components. The separating film has several protrusions for forming several flow channels between the separating film and each of the components. The bar supporting members are disposed in the flow channels, and extension directions of the bar supporting members are substantially parallel to extension directions of the flow channels. The bar supporting members are connected to sidewalls of at least some of the flow channels. The separating film has a thickness of smaller than 0.25 mm. Each of the bar supporting members is greater than a hardness of the separating film. The separating film is a metal thin film. A layer of anticorrosive material is disposed on a surface of the metal thin film. A liquid-repelling layer is disposed on a surface of the separating film.
