Modeling and simulation of hybrid auxiliary energy unit based on fuel cell/storage device

Traditional aircraft auxiliary power plant noise, large carbon emissions, low efficiency, has been unable to meet the multi-electric/Full-power aircraft development requirements.The fuel cell has the advantages of high energy density, zero emission, long service life, low noise and high efficiency.In this paper, a fuel cell model is established and optimized to better reflect its steady and transient performance in.A hybrid system composed of fuel cell and super capacitor is established as a model of aircraft auxiliary Energy Unit, which verifies that the power quality satisfies the gjb181a-2003 Standard, and compares with the traditional auxiliary power plant, showing its response speed,Efficiency and work-weight ratio have obvious advantages.
