Regardless of hysteresis of air system, the main factor that influences dynamic response of fuel cell is diffusion concentration polarization, which restricts the change rate of stack current.

不考虑空气系统的时间滞后，影响电池动态响应时间的主要因素为扩散浓差极化，它限制了电流的变化率。

If there's a group, responsibility to help decreases and this is captured in different ways but the main idea is we all think someone else will help so we don't. There's a diffusion.

如果是一群人，帮助的责任就会分散变小,这体现在多个方面,但最主要的想法就是我们都认为别人会帮助,所以我们就不帮助了，责任被分散了。
