Use of ultrasonic processes for catalyst layer transfer in catalyst coated membrane manufacture

未来汽车市场对膜电极组件（mea）的需求是如此之大，以至于需要在制造过程中向连续工艺转变。这种工艺的瓶颈来自于将催化剂层贴花转移到质子交换膜以形成催化剂涂层膜（CCM）的过程中所使用的耗时和耗能的热量和压力过程。该项目将研究在创新、更快、更有效的贴花转移过程中使用超声波能量作为替代热源的可行性。将评估这种工艺在连续的卷对卷CCM生产线上的应用。

The demand for membrane electrode assemblies (MEAs) from a future automotive market is such that a step change in manufacturing towards continuous processes will be required. A bottleneck in such a process results from the time- and energy-consuming heat and pressure processes used in decal transfer of the catalyst layer to the proton exchange membrane to form the catalyst coated membrane (CCM). This project will investigate the feasibility of using ultrasonic energy as an alternative heat source in an innovative, faster and more efficient decal transfer process. The application of such a process to a continuous reel-to-reel CCM manufacturing line will be assessed.
