求翻译：Aalto大学研究人员通过采用原子层沉积(ALD)法制取纳米粒子催化剂，使得燃料电池的阳极催化剂覆盖层可比以前薄得多，催化剂需要量减少60%，能够显著降低成本，提高质量。研究结果表明，采用该方法制备的贵金属纳米粒子催化剂与目前商业燃料电池催化剂相比，具有较低催化剂负载，但却能提供类似的活性。是什么意思？

aalto university researchers through the use of atomic layer deposition (ald) the preparation of nanoparticle catalysts, fuel cell anode catalyst coverage is much thinner layer than the previous, the requirement of catalyst reduced by 60%, can significantly reduce costs, improve quality. The results

Researchers at the University Aalto through use of atomic layer deposition (ALD) rule the particles act as a catalyst to make the fuel cell anode catalyst coating can be much more than in the past, the catalyst is red
