摘　　要：氢燃料电池的兴起为氢气纯化领域带来新的挑战。氢气中痕量硫化氢(H_(2)S)对燃料电池中Pt/C催化剂的不可逆毒化作用,推动了H_(2)S深度脱除的研究工作。但目前能达到燃料电池级氢气要求的H_(2)S脱除研究的报道相对较少,通过对常规H_(2)S的吸附脱除研究现状进行系统梳理,重点概述沸石分子筛如斜发沸石、A型、X型、Y型和其他类型分子筛及其改性分子筛在H_(2)S吸附脱除领域的研究进展,简要介绍本课题组在H_(2)S深度脱除方面的研究进展,以期为燃料电池中氢的纯化提供技术思路。The emerging of hydrogen fuel cells has brought new challenges to the field of hydrogen purification.The irreversible toxication of trace H_(2)S in hydrogen on Pt/C catalysts in fuel cells has promoted the research of deep H_(2)S removal.However,there are relatively few reports on the research of H_(2)S removal that can meet the requirements of fuel cell grade hydrogen.Through systematically reviewing the research status of conventional H_(2)S adsorption and removal,the paper focuses on the research progress of zeolite molecular sieves such as clinoptilolite zeolite,A-type,X-type,Y-type and other types of molecular sieves and their modified molecular sieves in the field of H_(2)S adsorption and removal,and briefly introduces the research progress of the research group in deep H_(2)S removal,so as to provide technical ideas for the purification of fuel cell hydrogen.
