Review of Fuel Cell Power Converter Topologies for Electric Vehicles

Fuel cells are electrochemical energy transformation devices that use redox reactions to convert the chemical energy of the fuels to electrical energy. Fuel cells are stacked together for high-power applications, and they are interfaced with power con-verters to meet the application requirements. The requirements of the power converters for fuel cell electric vehicles (FCEV) are as follows: minimum ripple in the fuel cell output current, lower size and weight, low cost, and high efficiency. The main objective of this paper is to present a review of state-of-the- art fuel cell dc-dc converters for FCEV s. The existing fuel cell power converter topologies are divided into different categories, and their advantages and disadvantages are presented. Based on the study, some important conclusions are drawn and mentioned for future studies in this area.
