WODOROWE OGNIWA PALIWOWE WYKONANE Z WYKORZYSTANIEM TECHNOLOGII PRZYROSTOWYCH (DRUKU 3D)

The article presents issues related to hydrogen fuel cells. It focusses primarily on the construction of fuel cells with a proton exchange membrane. The tasks performed by individual components are indicated and their basic properties are listed. Particular attention was paid to bipolar plates. On the basis of the possibilities of using additive technologies for the production of plates, a plate design was proposed that would allow the construction of a single fuel cell. It was assembled using a ready-made membrane-electrode assembly MEA and printed other elements. The fuel cell operation tests allowed to determine the voltage-current characteristics and efficiency. Taking into account the possibilities of making elements using additive technologies, bipolar plates with internal cooling channels were designed for use in the fuel cell stack.
