Research on PEMFC and its interface converter

With the continuous expansion of energy storage market, proton exchange membrane fuel cell (PEMFC) technology using hydrogen as fuel has attracted more and more attention. However, the market of hydrogen fuel cell still faces many difficulties, and the design methods of the corresponding converter are still immature. In this paper, the topology and control strategy of DC/DC converter for PEMFC are discussed. It is found in this paper that the converter of hydrogen fuel cell is similar to the conventional converter in general, but special design is needed to deal with the dynamic response in order to meet the operation requirements and prolong the life of the converter.
