A fuel cell-based hybrid power supply for portable electronics devices

Abstract

A fuel cell - supercapcitor hybrid power supply for portable applications is designed. To ensure system level simulation, each component is accurately modelled and simulation results are reported. A Digital Still Camera is selected as specific load device, although the choice of a specific application does not influence the proposed control technique performances but only dictates the power supply specifications. The fuel cell and the power management system are modelled in PSIM.
