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.

Happy dog
Flavor Name: Chicken, Size: 12 Ounce (Pack of 1)
We have a big dog and don't like to give him rawhide products for many reasons. We came across SmartBones a couple of years ago and have bought them ever since. They work well for our dog. The challenge has been finding them in stores where we live and at a fair price. These worked.

Flavor Name: Chicken, Size: 12 Ounce (Pack of 1)
I order these a lot. They don't have rawhide in them so that is my main reason. I have a small dog and I order a large because it then takes him about 45 mins to an hour to eat. Most of the time after he eats half I save the other half for the next day to make them last longer! He is a very active dog but these are his favorites. I also order them in small for little treats here and there (those last under 10 mins for him).

Dog loves even though they are thin product dog loves them and Picks Them out of many many toys.
These were super thin and I thought about tearing a hole in them and putting in a slight bit of stuffing. However, my dog absolutely loves them and we fling them across the house and the yard like little Frisbees. They are very lightweight but kind of a corduroy stitched fabric and they have lasted quite some time and been through the washer and dryer many times and abused. Still holding up and the dog loves them. Highly recommend a great product for the price.

Will Buy Again--Eventually as they are hearty
My dog loves these "trash babies" as the size, squeaker & trash /cellphane sound the crinkle toy makes brings her joy. this brings me joy as the stitching is hearty and toys hold up when cleaned in my washing machine & dryer. Her first trash baby is still going strong after a year tho the crinkle sound has dimminshed some the sweaker is good as new. I bought these to rotate to wash and keep a new one for travel. Very durable! good size for my 20 pound mini aussie.

Cute, big enough and top notch quality
These are SO CUTE! The look exactly like the pictures so I am really glad about that. They are quite substantial in size, big enough. See pics :). I gift one of three to my friend's dog. The texture is soft and boucle like and soothing for me and the doggos! The squeakiness is very prominent but not present in all parts of the toy - so its annoying. I am also glad these have no stuffing because they look great as is and lack of the stuff make them easy to chew on. The cuteness got me on this one and I may repurchase again, if need be.
