GOMEA: A Conceptual Design of a Membrane Electrode Assembly for a Proton Exchange Membrane Electrolyzer
نویسندگان
چکیده
We are proposing a conceptual membrane electrode assembly (MEA) of proton exchange water electrolyzer that includes layer graphene oxide (GO) at the cathode side. This GO primarily reinforces MEA to allow operation higher pressure difference between and anode Additional benefits would be perfect prevent both hydrogen crossover thus for pure, dry escaping directly from without losses due crossover, eliminating need clean-up steps. The mechanical strength will also thinner polymer electrolyte could save cost. Finally, effect electro–osmotic drag on content in such an is discussed, it argued lead oversaturated membrane, which highly desirable.

Studies 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...
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...

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Three Dimensional Computational Fluid Dynamics Analysis of a Proton Exchange Membrane Fuel Cell
A full three-dimensional, single phase computational fluid dynamics model of a proton exchange membrane fuel cell (PEMFC) with both the gas distribution flow channels and the Membrane Electrode Assembly (MEA) has been developed. A single set of conservation equations which are valid for the flow channels, gas-diffusion electrodes, catalyst layers, and the membrane region are developed and numer...
