技術說明

本發明揭露一種燃料電池及燃料電池的製造方法。燃料電池包含兩個固定件、多個電極板、多個內鈦網結構、多個外鈦網結構、多個膜電極組、多個觸媒層及多個密封環。各個電極板的一側通過擴散焊接技術固定有一個內鈦網結構。部分的電極板的另一側通過擴散焊接技術固定有一個內鈦網結構。各個內鈦網結構與電極板共同形成多個流道。各個內鈦網結構的另一側固定有外鈦網結構。各個外鈦網結構的一側設置有觸媒層。各個膜電極組位於兩個外鈦網結構之間，而各個外鈦網結構作為氣體擴散層。 The invention discloses a fuel cell and a manufacturing method of the fuel cell. The fuel cell includes two fixing parts, a plurality of electrode plates, a plurality of inner titanium mesh structures, a plurality of outer titanium mesh structures, a plurality of membrane electrode groups, a plurality of catalyst layers, and a plurality of sealing rings. An inner titanium mesh structure is fixed on one side of each electrode plate by diffusion welding technology. Each inner titanium mesh structure and the electrode plate together form a plurality of flow channels. An inner titanium mesh structure is fixed on the other side of part of the electrode plate by diffusion welding technology. An outer titanium mesh structure is fixed on the other side of each inner titanium mesh structure. A catalyst layer is provided on one side of each outer titanium mesh structure. Each membrane electrode group is located between two outer titanium mesh structures, and each outer titanium mesh structure serves as a gas diffusion layer.
