NOVELTY - The channel module (100) comprises a first carrier (110) having a channel opening (112) and a Y-shaped channel (114), a second carrier (120) disposed on the first carrier, and a cover that is disposed on the second carrier and has sub-openings, a protrusive portion and locking elements. The channel opening communicates with the channel. The second carrier has an accommodation cavity and a main opening (124) that is located at the geometry center of a bottom surface of the accommodation cavity, where the accommodation cavity communicates with the channel through the main opening.    USE - The channel module is useful in a fuel cell for diverging or converging a liquid fuel (claimed) into fuel modules to generate electric power, where the fuel cell includes proton exchange membrane fuel cell or direct methanol fuel cell.    ADVANTAGE - The channel module is capable of evenly, rapidly and smoothly diverge or converge the liquid fuel into fuel modules with enhanced velocity of flow by avoiding an excessive flow resistance caused by piling of bubbles thus providing a stable electric power with improved performance.    DETAILED DESCRIPTION - The channel module (100) comprises a first carrier (110) having a channel opening (112) and a Y-shaped channel (114), a second carrier (120) disposed on the first carrier, and a cover that is disposed on the second carrier and has sub-openings, a protrusive portion and locking elements. The channel opening communicates with the channel. The second carrier has an accommodation cavity and a main opening (124) that is located at the geometry center of a bottom surface of the accommodation cavity, where the accommodation cavity communicates with the channel through the main opening. The sub-openings communicate with the accommodation cavity. The locations of the sub-openings are on a same plane and form a geometry shape, and the orthogonally projected location on the plane of the main opening is the geometry center of the geometry shape. The bottom surface of the accommodation cavity is an arc surface. The protrusive portion is located in the accommodation cavity. An accommodation space is located between the protrusive portion and the accommodation cavity, and communicates with the channel through the main opening. The sub-openings communicate through the protrusive portion and with the accommodation space. A shape of the protrusive portion is similar to the shape of the accommodation cavity. The second carrier comprises sub-channels that are located at the bottom surface of the accommodation cavity, and a buffer concave portion that takes the main opening as the center. The second carrier communicates with the main opening, where the sub-channels extend to the sub-openings from the main opening as a radial center. Each of the sub-openings communicates with the main opening through the corresponding sub-channel. A maximum sectional area of the buffer concave portion is equal to 0.8-1.2 times as large as the sum of the sectional areas of all the sub-openings. The sum of the sectional areas of the sub-openings is equal to the maximum sectional area of the buffer concave portion. The locking elements are located at a side of the cover far away from the second carrier. An INDEPENDENT CLAIM is included for a fuel cell.
