摘　　要：一体式可再生燃料电池是可再生燃料电池中最先进的一种,它是在同一组件上既可以实现燃料电池功能又可以实现水电解功能的储能和供电系统,具有能量密度高、使用寿命长、使用中无自放电且无放电深度及电池容量的限制等优点,是极有希望在空间、军事及可移动电源领域替代传统二次电池的储能系统。本文介绍了一体式可再生燃料电池的研究进展,并提出了目前亟待解决的问题。The unitized regenerative fuel cells （URFCs） are the most advanced regenerative fuel cells （RFCs）, which use reversible PEM cells, where each cell is capable of operating both as a fuel cell and as an electrolysis cell. They are particularly very promising energy storage systems to replace traditional secondary batteries for space application since URFCs have distinctive advantages over secondary batteries in that they are long-term energy storage systems with extreme high specific energy and without permanent losses by self discharge and capacity limit. They are enabling for many weight-critical portable applications such as space and military energy storage and conversion systems, as well as remote （off-grid） power sources .In this paper, the recent progress of unitized regenerative fuel cells is introduced, and the issues need to be developed or solved are also put forward.
