Study on operating characteristics of fuel cell powered electric vehicle with different air feeding systems

Abstract

In this paper the modeling of a fuel cell powered electric vehicle is presented. The fuel cell system consisting of a proton exchange membrane (PEM) fuel cell stack and balance of plant (BOP) was co-simulated with a commercial vehicle simulation program. The simulation program calculates the load of the fuel cell depending on the driving mode of the vehicle and also calculates the overall efficiency and each parasitic loss by applying the load in the fuel cell model that is used to estimate the performance of the entire vehicle system by calculating the acceleration performances and fuel economy of the vehicle. Two types of air feeding systems (blower type and compressor type) were modeled by using MATLAB/Simulink environment and the effect of fuel cell stack size (number of cells, cell area) on the fuel economy and performance of the fuel cell powered vehicle was investigated. Using a driving cycle of FTP-75, the required power, BOP component power loss, and system efficiency for two types of fuel cell systems were analyzed. Through this study, we could get a basic insight into the fuel cell powered electric vehicle and its characteristics.

Improvement in physical properties of single-layer gas diffusion layers using graphene for proton exchange membrane fuel cells

“…It is known that the performance efficiency of PEMFCs is related to the FC system used and the parameters applied. Each parameter used in the PEMFC such as the material of PEM, 2,6 fuel gas flow rate, 32 inlet air temperature and relative humidity, 33 different humidifier systems, 34 the type of flow field plate, 35 humidification temperature and cell temperature, 36 compression pressure and water management, 37 and catalyst, 38 can affect the performance.…”

“…Ф ca,in 0.6(-1) 0.8(0) 1 (1) ables represent the dependent ones that affect a certain response due to the reaction of the design variables.…”

“…Compared with other alternative energy sources such as wind power, solar energy, and tidal energy, the fuel cell, which uses hydrogen energy, has been more adverted to because of its environmental friendliness, high efficiency, low noise, and low vibration. Recently, Polymer Electrolyte Membrane Fuel Cell (PEMFC) has been widely studied for its use as a power source in automobiles or small-sized generators due to its comparable low power output, low operating temperature, high efficiency, high current density, and structural safety compared with other fuel cell systems [1]. However, to fully commercialize this technique, it is still necessary to maximize its operating power and minimize the cost.…”

Parameter Study on Cooling System of Battery for HEV

“…Recently, a hybrid power composed of the fuel cell and MH-Ni battery has become a good strategy for HEV. But, the produced heat of batteries can effect to the performance of the HEV significantly [1][2][3]. So, cooling system of battery should be designed well for adjusting the temperature distribution of battery pack [4][5][6].…”
