This work evaluates the success of application proton-exchange membrane fuel cells for transportation with a focus on issues and areas possible developments. Fuel cell technology when applied in road, air water all instances had contributed to provision cleaner environment. The new technology, if developed, would meet economic prospect people. If cost materials, labour overhead could be reduced...

The problem of parameter estimation the proton exchange membrane fuel cell (PEMFC) model plays a significant role in simulation and optimization PEMFC system. In current research, moth flame algorithm (MFOA) is used to identify best parameters PEMFC. Two different PEMFCs, Nedstack PS6, 6 kW, SR-12 PEM 500 W are demonstrate accuracy MFOA. Throughout process, seven unidentified (℥1</s...

Proton exchange membranes (PEMs) play an important role in the fuel cell systems. A good PEM must meet a series of requirements such as high proton conductivity, excellent mechanical strength and stability, chemical and electrochemical stability, low fuel crossover, etc. Nafion is currently the most commercially utilized electrolyte membranes for polymer electrolyte fuel cells, with high chemic...

Anion exchange membrane (AEM) electrolysis aims to combine the benefits of alkaline electrolysis, such as stability cheap catalyst and advantages proton-exchange systems, like ability operate at differential pressure, fast dynamic response, low energy losses, higher current density. However, today, AEM is limited by AEMs exhibiting insufficient ionic conductivity well lower activity stability. ...

A novel Na/H exchange activity that requires Cl was recently identified in the apical membrane of crypt cells of the rat distal colon. This study explores the nature of the coupling of Cl and Na/H exchange. A concentration of 100 μM 5-nitro-2-(3-phenylpropylamino)benzoic acid, a Cl channel blocker, inhibited the Cl dependence of both proton gradient-driven22Na uptake from crypt cell apical memb...
