Patent ID: 10205180

Abstract:
A passive direct liquid fuel cell is provided, which relates to a fuel cell field, including a current-collector-integrated fuel tank unit and a sealing-fastening-integrated current-collector which are prepared via a three-dimensional (3D) printing technology. The current-collector-integrated fuel tank unit is fastened with the sealing-fastening-integrated current-collector, and a membrane electrode assembly is sandwiched between the current-collector-integrated fuel tank unit and the sealing-fastening-integrated current-collector. Because of designs of current collectors, a fuel tank and a sealing fastening manner, an integration of the current collectors, the fuel tank and fasteners is realized. The current-collector-integrated fuel tank unit and the sealing-fastening-integrated current-collector are rapidly formed via the 3D printing technology, so that the whole fuel cell has a compact and simple structure, a lighter weight and a smaller volume.
