    • PURPOSE: Manufacturing apparatus of a membrane-electrode assembly is provided to directly spray catalytic materials to a metal roll drum by using electrospray process, thereby capable of electrode patterning through voltage control, and to improve electrode production yield by uniform distribution and high porosity of a catalytic layer. CONSTITUTION: Manufacturing apparatus of a membrane-electrode assembly comprises: many sprayers(10,12) receiving and storing catalyst slurry; a pair of metal drums(20,22) in which the catalyst slurry sprayed from the sprayers is spread; a voltage supply source(30) applying voltage to each metal drum and the sprayer; and a heater for drying the catalyst slurry spread on the surface of the metal drum by being installed in the metal drum. A pattern(24) determining the size and the shape of the catalyst layer(50) on the surface of the metal drum.
    • 目的:提供膜 - 电极组件的制造装置,通过使用电喷雾法将催化材料直接喷射到金属辊滚筒,从而能够通过电压控制进行电极图案化,并且通过均匀分布和高孔隙率提高电极产生产率 催化层。 构成:膜 - 电极组件的制造装置包括:许多喷雾器(10,12),接收和储存催化剂浆料; 一对金属桶(20,22),其中从喷雾器喷射的催化剂浆料被扩散; 电压源(30)向每个金属鼓和喷雾器施加电压; 以及加热器,用于通过安装在金属滚筒中来干燥在金属滚筒的表面上扩散的催化剂浆料。 确定金属滚筒表面上的催化剂层(50)的尺寸和形状的图案(24)。
