The invention provides a fuel cell stack with a multilayer type collector plate, the fuel cell stack comprises: an end plate which is arranged on two sides of a row of stacked cells to fixedly support the stacked cell; and current collectors which are arranged in the end plate to collect electric power generated by stacked cells and is configured to transmite the electric power to the outside, wherein at least one of the current collectors on two sides of the stacked cells comprises a first collector plate which comprises a collector terminal and a second collector plate which is stacked on one surface of the first collector plate, thermal contraction occurs in stacked cells at a temperature under zero, so tha a gap for heat insulation is formed between the first collector plate and the second collector plate. 本发明提供种具有多层型集电板的燃料电池堆，包括：端板，布置在堆叠成排的堆叠电池的两侧，以固定地支撑所述堆叠电池；以及集电体，布置在端板内，以收集由堆叠电池产生的电力，并被配置成将电力输送到外部，其中，置于堆叠电池两侧的集电体中的至少个集电体包括：具有集电端子的第集电板，以及堆叠在第集电板的个表面上的第二集电板，并且由于堆叠电池在零度以下的温度下发生热收缩而在第集电板与第二集电板之间形成起绝热作用的间隙
