Proton exchange membrane fuel cells have been receiving more and more attention these recent years. Maintaining a fuel cell system in correct operating conditions requires good controller. Based on the mathematical model of proton exchange membrane fuel cells described in this paper, the fuzzy logic controllers was designed for the proton exchange membrane fuel cell to make it possible to outpu...

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. ...

Anion-exchange membrane water electrolyzers (AEMWEs) are prepared as catalyst-coated membranes using varying amounts of ionomer in the catalyst layers.

We previously demonstrated, using fluorescence recovery after photobleaching, that clathrin in clathrin-coated pits at the plasma membrane exchanges with free clathrin in the cytosol, suggesting that clathrin-coated pits are dynamic structures. We now investigated whether clathrin at the trans-Golgi network as well as the clathrin adaptors AP2 and AP1 in clathrin-coated pits at the plasma membr...

Most mechanisms involved in neuronal maintenance and function are activated at the membrane. Membrane-related molecular agents, which interact protein/lipid clusters to begin processing signal transduction, required for these functions. Furthermore, many neuropathological disorders originate this structure and/or result of membrane malfunction. Although precise maintaining "membrane health" unk...

Efficiency of a sequential ultrafiltration – ion exchange purification system was studied by testing separation of an anionic surfactant (SDBS) from aqueous solutions. Commercially available ultrafiltration membranes with cut-off values of 5, 10, and 30 kDa were used for the tests. The ion exchange processes were carried out on five types of ion-exchange resins – both macroporous and gel-based....

The performance of an alternative membrane based on aromatic multiblock copolymer was compared to that the conventional perfluorosulfonic acid (PFSA) polymer during fuel cell operation. with exhibited more severe voltage loss than at current densities above 0.6 A/cm2 fully saturated reactants. To rationalize this difference, operando high-resolution neutron imaging used investigate water distri...
