This paper reviews the state-of-the-art of mitigation technologies of low frequency current ripple (LFCR) injected into fuel cell (FC). Although there are their own merits and demerits, the optimized LFCR control techniques and topology structures are characterized in many aspects like performance, durability, reliability and lifetime of FC. Three mains topologies and mitigation methods of LFCR have been investigated based on the literature review, which are the passive compensation methods, active compensation methods, and passive and active hybrid compensation methods. Some rules based tables are set to evaluate the LFCR against the topologies, control strategies, current ripple, application and advantages/limitations. Moreover, the mitigation control strategies are compared side by side with their specific applications in FC system. To select and implement them, this review can provide a reference and basis for the researchers in related fields. Finally, a case study in an uninterruptible power supply application is conducted. •Generation mechanism and performance effect of low frequency current ripple (LFCR).•A review on three main types of LFCR mitigation technologies in fuel cell (FC).•A case study with passive and active hybrid LFCR compensation method.•A reference and basis for the researchers in the related fields of LFCR and FC.
