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.

未来汽车市场对膜电极组件（MEA）的需求使得制造过程需要向连续工艺进行阶段性变化。这种方法中的瓶颈是由在催化剂层到质子交换膜的贴花转移中使用的耗时和耗能的热和压力方法导致的，以形成催化剂涂覆的膜（CCM）。该项目将研究使用超声波能量作为替代热源在创新，更快，更有效的贴花转印过程的可行性。将评估这种工艺在连续卷到卷CCM生产线上的应用。
