Name: Proton Exchange Membrane Pretreatment

Product Overview

 

Proton Exchange Membrane (PEM) is an ion selective membrane that provides channels for proton migration and transport, separates gas reactants, and blocks electrolytes in batteries. Proton exchange membrane, also known as proton membrane or hydrogen ion exchange membrane, is a polymer material based on proton conduction. It can transfer hydrogen ions from the anode to the cathode inside the battery, forming a circuit with the transfer of electrons from the external circuit, thereby providing current to the outside world. The Nafion membrane and perfluorosulfonic acid proton exchange membrane developed by DuPont in the United States are currently the most representative types of proton exchange membranes. It has excellent proton conductivity, chemical stability, and mechanical strength.

Product Features


High proton conductivity: to ensure that the battery has efficient energy conversion efficiency.

Low gas permeability: effectively separates the reactive gases of the anode and cathode, avoiding direct contact between them.

High chemical stability: able to maintain stability during battery operation without being corroded by electrolyte or reactive gases. High thermal stability: able to maintain stable performance at higher operating temperatures.

High mechanical strength and dimensional stability: to ensure that the battery's performance will not be affected by membrane deformation or damage during long-term use.


Application Fields

 

Fuel cell: As the core component of proton exchange membrane fuel cell (PEMFC), it plays a crucial role in the performance of the cell. PEMFC has the advantages of high efficiency, environmental protection, and no noise, and has been applied in fields such as automobiles and ships.

Water splitting: As an ion selective channel, it promotes the H+ions in water molecules to move towards the anode and react with the electrode to produce hydrogen gas, achieving a clean and renewable hydrogen production method.

Membrane separation technology: applied in fields such as wastewater treatment and seawater desalination, it separates different ions through proton exchange membranes.

Environmental protection and biomedicine: used in the field of environmental protection to reduce harmful substance emissions; As a drug delivery system in the field of biomedicine, it controls drug release rate and improves stability.

Nice shirt, great price.
Fit Type: Regular Fit, Color: White, Size: Medium
Worn it twice and I find it very comfortable. I wear it outside and casually to protect my arms and neck from the sun and find it more comfortable than a long sleeve t-shirt. The price is comparable. If I was to wear it to the office it would have to be ironed. I bought one shirt to try it and I will be buying more.

Nice shirt!
Fit Type: Regular Fit, Color: White, Size: X-Large
I added one of these shirts to another order just to see if they were any good. I was pleasantly surprised by the quality. It fits perfectly and looks pretty nice for a low cost casual dress shirt. Materials seem decent quality. Comfortable, soft fabric. Didn’t shrink too much in the washer and dryer. We’ll see how it holds up long term but so far so good

My new favorite shirts!
Fit Type: Regular Fit, Color: Grey, Size: Large
These are my new favorite shirts! I just ordered a 3rd. i wish there were more colors. Yes, the cotton is heavy-weight and I like that. They are just a bit warmer than regular dress shirts. The fit is excellent. I'm 5'9", 200lbs and L fits perfectly. Enough room without being blousy. The sleeves are long enough (finally!). (Most other 16.5/32-33 shirts always have sleeves that are too short). The fit/finish and detail is surprisingly good. They don't really shrink after washing and come out very soft. Not wrinkle-free, but that's ok since it means that the 100% cotton hasn't been dosed with chemicals. I expect they will wear very well over time.
