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

At this step, you need to use the tools discussed above to get statistics on the query: its responsetime, its detailed execution plan, and costs for later in-depth analysis.
