45 kW质子交换膜燃料电池发动机建模与仿真
Modeling and Simulation of a 45 KW Proton Exchange Membrane Fuel Cell Engine
摘要
Abstract
A mathematic model for a 45 kW proton exchange membrane fuel cell (PEMFC) engine system was established, including a fuel cell stack and a reacting gases supply subsystem as well as a water/thermal management subsystem. An error correction term was introduced to improve model accuracy in calculating the stack voltage. Subsequently, the model was validated experimentally. The coolant temperature at stack inlet, air excess ratio and air pressure at cathode inlet were employed as the manipulating variables, meanwhile, the corresponding sensitive analysis and systematic response were made under the given current densities. The simulation results show that the coolant temperature at stack inlet was proposed to reduce appropriately, while the air pressure at cathode inlet to be regulated as high as possible to obtain a better performance of the PEMFE engine system; in order to maintain rational stack temperature, the water/thermal management subsystem should be controlled effectively.关键词
