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 thegjb181a-2003Standard, and compares with the traditional auxiliary power plant, showing its response speed,Efficiency and work-weight ratio have obvious advantages.

Progress in Energy & Fuels, Vol.4, No.1, 2024; 138 Views, 2 PDF Downloads

Resources is a key factor in the selection of biomass energy materials,external constraints affect biomass energy development pathselection.from an international perspective, the development process of biomass energy in China is affected by factors other than resource ,in a self-sufficient pattern of food supply,validates that our country is using food crops,sugar crops and oilseed production organismsThe conclusions of the energy source may lead to food security problems.China in the process of urbanization and industrialization,development of biomass energy nullbetween large,developing non-grain energy crops can meet the demand of economic growth,to avoid food security threats.throughestimatesknow,scattered marginal land distribution and energy crop differentiation growth space requirements our country to adopt a variety of non-grain energysource crop cropping strategy
