In this article a CCHP system has been proposed for recovering waste heat of PEM fuel cell and this system can be used for residential applications. Main components of the system are PEM fuel cell, absorption chiller, fuel processor and heat storage tank. Electrochemical equations of PEM have been modeled by MATLAB and the chiller, fuel processor and boiler have been modeled by EES. In addition...

The fate of extracellular glucose in blood isolated from sea raven (Hemitripterus americanus) and rainbow trout (Onchorhynchus mykiss) was determined. In blood from both species incubated in vitro at low physiological pH, the decrease in plasma glucose concentration was more than adequate to support oxygen consumption. Glucose disappearance could not be accounted for by increases in lactate, re...
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 injection into the anode and cathode reaction area field have been introduced. they consist of one inlet and two inlets and also a continuous channel. the governing equations on t...
hydrogen can be produced for fuel cell applications by using methanol steam reforming reaction. in this article, a method was developed for regeneration of accelerated deactivated methanol-steam-reforming catalyst. successive deactivation–regeneration cycles were studied in a 250 hours test for the first time including 6 regeneration cycles. it is shown that regeneration of the catalyst in dilu...
nano-structured lanthanum strontium cobalt ferrite, la0.6sr0.4co0.2fe0.8o3 (lscf), was successfully synthesized via co-precipitation method using metal nitrates as starting materials. effects of precipitating agent and calcination temperature on the phase composition and morphology of synthesized powders were systematically studied using x-ray diffraction (xrd) and field emission scanning elect...
the renewable energy sources and plug-in electric vehicles (pevs) are becoming very popular because of the combination of high fuel costs and concerns about emission issues. this paper presents modelling and control of a building integrated fuel cell and plug-in electric vehicles (bifc-pev) in smart distribution systems. in bifc-pev system, conventional building elements could be replaced by sp...
in present research work, homogeneous anion exchange membranes based on polysulfone (qapsfs) were prepared via chloromethylation, amination and alkalization. in amination step, trimethylamine and n,n,n',n'-tetramethyl-1,6-hexanediamine were used as amination and crosslinking agents, respectively. the chloromethylated polysulfone was characterized by 1hnmr spectroscopy and chloromethylation degr...
development of efficient electrocatalysts for oxygen reduction reaction (orr) is one of the most important issues for optimizing the performance of fuel cells and metal-air batteries. the introduction of nitrogen into carbon nanostructures has created new pathways for the development of non-precious electrocatalysts in fuel cells. in this work, nitrogen-doped graphene (ng) was synthesized by a ...
