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.

Extremely Overpriced
Number of Items: 4
It doesn’t hold charge too long , especially if it’s not on a perfectly bright sunny day without clouds. Even at that , It will only be able to light up for maybe two or three hours at best , and not very bright at all. Construction and materials are of good quality that’s why the one start or else zi would gave given a zero if i could. it is way overpriced for what it is. I am disappointed for what I paid and the amount of production I get from it. Would have returned it if I haven’t installed them and threw away the boxes.

Very durable and designed to last a long time
Number of Items: 2
I've had a pair of these lights for 7-8 years and would still be using them with no issues if a naughty racoon hadn't taken an interest in them and broken the glass on one of them. I was delighted to find that the identical looking ones (operate slightly differently) were still available. They are extremely simple to put together (just screw together the durable metal pieces) and turn them on to the chosen brightness. It couldn't be much simpler. I also have other Gama Sonic solar lights and they are every bit as good.
