Development of Glassy Alloy Separators for a Proton Exchange Membrane Fuel Cell (PEMFC)
The Ni60Nb15Ti15Zr10 glassy alloy was developed as a separator material for a proton exchange membrane fuel cell (PEMFC). The corrosion rate of the glassy alloy in sulfuric acid was approximately 3 digits lower than SUS316L. A precise groove forming of the glassy alloy can be achieved by hot-pressing in the supercooled liquid state. The result of the power generation test of the single cell ass...
متن کاملNeural Network Modeling for Proton Exchange Membrane Fuel Cell (PEMFC)
This paper presents the artificial intelligence techniques to control a proton exchange membrane fuel cell system process using particularly a methodology of dynamic neural network. The focus of this study is to derive a non-parametric empirical model. Also it will include process variations to estimate the performance of fuel cells without extensive calculations. The ANN model has been validat...
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 کاملAn 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 کاملStudies on the SPEEK membrane with low degree of sulfonation as a stable proton exchange membrane for fuel cell applications
Sulfonated poly (ether ether ketone) (SPEEK) with a low degree of sulfonation (DS = 40%) was prepared for proton exchange membrane fuel cells (PEMFC). Poly (ether ether ketone) (PEEK) was sulfonated in concentrated H2SO4 under N2 atmosphere and characterized by the hydrogen nuclear magnetic resonance (H-NMR) technique. After preparation of the SPEEK polymer, the obtained polymer was dissolved i...
