Summary:To provide a water storage tank unit for fuel cell unit capable of efficiently thawing water, which is frozen in a water storage tank, even while efficiently diluting an anode off-gas.SOLUTION: A water storage tank unit U1 for fuel cell unit comprises a water storage tank 30 and a gas introducer 40. The water storage tank 30 includes a cathode off-gas introduction port for introducing a cathode off-gas into the water storage tank 30. The gas introducer 40 includes an anode off-gas exhaust port H3 communicating a stagnation chamber S2 with the inside of the water storage tank 30. The water storage tank unit U1 for fuel cell unit comprises an exhaust port through which a cathode off-gas and an anode off-gas are exhausted from the inside of the water storage tank 30 to the outside.SELECTED DRAWING: Figure 3 【課題】アノードオフガスの希釈を効率良く行いつつも、貯水タンク内で凍結した水の解凍を効率良く行うことができる燃料電池ユニット用貯水タンクユニットを提供すること。【解決手段】燃料電池ユニット用貯水タンクユニットU1は貯水タンク30と、ガス導入器40と、を有する。貯水タンク30は、カソードオフガスを貯水タンク30の内部に導入するカソードオフガス導入口を有する。ガス導入器40は、滞留室S2と貯水タンク30の内部とを連通させるアノードオフガス排出口H3を有する。燃料電池ユニット用貯水タンクユニットU1は、カソードオフガスとアノードオフガスの混合ガスを貯水タンク30の内部から外部に排出する排気口を有する。【選択図】図3
