The invention relates to the technical field of cooling liquids, in particular to a cooling liquid for hydrogen fuel cell automobiles, which comprises the following components: a base liquid and an antirust agent, the base liquid comprises deionized water and an antifreezing agent, the antifreezing agent is monohydric alcohol or dihydric alcohol, and the antirust agent is an organic solvent. The antirust agent comprises one or a combination of more of a triazole compound, an imidazole compound and a thiazole compound, an amide compound and a silicate ester compound, and the compound combination of the triazole compound, the amide compound and the estersil compound can achieve the same slow release effect as a traditional cooling liquid composition; the metal material of the fuel cell stack cooling system has excellent anti-rust performance while low conductivity is ensured.

    本发明涉及冷却液技术领域,具体为一种用于氢燃料电池汽车冷却液,包括以下组分:基础液和防锈剂,所述基础液包含去离子水和防冻剂,所述防冻剂为一元醇或二元醇,所述防锈剂包括三唑类化合物、咪唑类化合物和噻唑类化合物三者中的一种或多种组合以及酰胺类化合物、硅酸酯类化合物,本发明采用唑类化合物、酰胺类化合物和硅酯类化合物的复配组合可以达到传统冷却液组合物同样的缓释效果,在保证低电导率的同时提供对燃料电池电堆冷却系统的金属材料具有优异的防锈性能。
