结果表明：电池的启动时间和阶跃响应时间均为秒的数量级，与大多数模模拟的结果相一致。

It was found that the start-up and step response time of PEM fuel cell was in the order of seconds, which was similar to the simulation results of most presently used models.

在温度出现阶跃变化时，热电偶的输出变化至相当于该阶跃变化的50％所需的时间称为热响应时间，用T0.5表示。

Step change in temperature occurs when changes in the thermocouple output to the equivalent of 50% of the step change in the time required is called thermal response time, with T0.5 said.
