An analytic model of membrane humidifier for proton exchange membrane fuel cell
An essential requirement for an operating PEM fuel cell is providing proper water content in the membrane. To avoid water flooding an appropriate water balance is required. Here, an analytic model of a planar membrane humidifier for PEM fuel cell is proposed where the effect of dimensional parameters includes membrane thickness, membrane area and channel hydraulic diameter are investigated. A N...
متن کاملDynamic investigation of hydrocarbon proton exchange membrane Fuel Cell
Sulfonated polyether ether ketone (SPEEK) is categorized in a nonfluorinated aromatic hydrocarbon proton exchange membrane (PEM) group and considered as a suitable substitute for common per-fluorinated membranes, such as Nafion, due to wider operating temperature, less feed gas crossover, and lower cost. Since modeling results in a better understanding of a phenomenon, in this study a dynamic o...

متن کاملModel Predictive Control for the Proton Exchange Membrane Fuel Cell
Proton exchange membrane fuel cells are promising energy sources that produce electrical currents with almost null pollutant emissions, and they have been received growing attention in recent years. Maintaining a fuel cell system in correct operating conditions requires good system control. Based on the mathematical model of proton exchange membrane fuel cells, model linearization is carried ou...
متن کاملFuel cell model based on proton exchange membrane (PEM)
This paper presents the development of the electrical and mathematical models which is able to simulate the static and dynamic phenomena of proton exchange membrane fuel cell (PEMFC). The models were validated against the current distribution data experimentally measured earlier. A parallel computational methodology was employed to substantially reduce the computational time and to make large-s...
