Due to high power density and reactivity compared with the use of gaseous hydrogen as the fuel, direct borohydride fuel cell (DBFC) is becoming an emerging renewable energy source. In this paper, DBFC characteristic is analyzed based on the frequency response measurement and test with different load conditions. The equivalent circuit of DBFC is obtained from the DBFC characteristic. A dc-dc converter is designed from the frequency domain and verified its performance at time domain with transient load test. Based on the combined model analysis of DBFC and the dc-dc converter, transient response of the model is discussed. In addition, load transient response tests with power supply and DBFC have been compared. A prototype of dc-dc boost converter for 5-cell DBFC has been built and tested.
