Studies on the SPEEK membrane with low degree of sulfonation as a stable proton exchange membrane for fuel cell applications

Parnian, Mohammad Javad؛ Gashoul, Fatemeh؛ Rowshanzamir, Soosan (Iranian Research Organization for Science and Technology, 2016-08-01)

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 ...
Experimental Study on a 1000W Dead-End H2/O2 PEM Fuel Cell Stack with Cascade Type for Improving Fuel Utilization

Alizadeh, Ebrahim؛ Khorshidian, Majid؛ Masrori Saadat, Seyed Hossein؛ Rahgoshay, Seyed Majid؛ Rahimi-Esbo, Mazaher (Iranian Research Organization for Science and Technology, 2016-08-01)

Proton exchange membrane fuel cells (PEMFCs) with a dead-ended anode and cathode can obtain high hydrogen and oxygen utilization by a comparatively simple system. Nevertheless, the accumulation of the water in the anode ...
The effect of vertical injection of reactants to the membrane electrode assembly on the performance of a PEM fuel cell

Ramin, Farzin؛ Baheri Islami, Sima؛ Hossainpour, Siamak (Iranian Research Organization for Science and Technology, 2016-08-01)

In order to present a new and high performance structure of PEM fuel cell and study the influence of the flow direction and distribution on the rate of reactants diffusion, three novel models of vertical reactant flow ...
