Dynamic model of oxygen starved proton exchange membrane fuel-cell using hybrid analytical-numerical method

Autocorrelation standard deviation and root mean square frequency analysis of polymer electrolyte membrane fuel cell to monitor for hydrogen and air undersupply

“…Vijayaraghavan et al developed a hybrid analytical-numerical model to study oxygen starved PEMFC systems [37]. Their model is a unified model which takes into account transfer leaks under oxygen starved conditions [37]. The result matched well with observed experimental data.…”

“…Further fuel starvation leads to even higher interfacial potential and increased carbon corrosion [36]. Vijayaraghavan et al developed a hybrid analytical-numerical model to study oxygen starved PEMFC systems [37]. Their model is a unified model which takes into account transfer leaks under oxygen starved conditions [37].…”

Identifying Characteristic Frequencies in the Electrochemical Impedance of Ion-Exchange Membrane Systems

“…Impedance functions can also be applied in the small-signal dynamic modelling of electrochemical power sources, such as Li-ion batteries and fuel cells, including ion-exchange membranes, which are of particular importance due to the increasing incorporation of such devices into sophisticated electric and electronic systems [ 18 , 19 ]. Multiple studies on the dynamic response of ion-exchange membrane systems have been published in fields related to proton-exchange membrane fuel cells [ 20 , 21 , 22 , 23 ].…”

Model Predictive Control Based Hydrogen Excess Ratio Regulation With Circulating Pump For Polymer Electrolyte Membrane Fuel Cell

“…As the vehicle's operating conditions change, the demand for hydrogen in the fuel cell is also changing. If the hydrogen supply is not timely, the fuel cell will cause fuel starvation, resulting in a decrease in fuel cell output power and remaining useful lifetime which is disadvantageous for the safety and economy of fuel cells and the vehicles [1][2]. Therefore, it is significant to have fast and accurate control of the hydrogen supply system to ensure the output capacity and service life of the fuel cell.…”
