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.

Fits 2005 325xi
Size: 2002-2005 E46
Snapped perfectly into place. Zero play with the fit and hood hinge still just as accessible as oe grille. No trimming required. If you’re sick of snapping your grille back in every time you lift the hood, buy it! I also have the colored grill inserts and they snap on perfectly with no play. https://a.co/d/3F83eFx

Fit is perfect and these have a very nice glossy finish
Size: 2002-2005 E46
Fit is perfect and these have a very nice glossy finish, which looks much better than the matte finish. As others have said, the driver's side grill lacks a cut out where the hood latch pull handle swings out when you need to lift the hood (compare the driver's side grill with the existing grill to see location and size of the cut out). I was able to cut an opening within 10 minutes and I haven't had any problems opening the hood since the installation.

Nice Finish, Decent Fit
Size: 2002-2005 E46
The fitment isn't perfect like the OEM grilles, but overall I was satisfied. These are just slightly smaller than the originals so there is a little play once installed. No need to modify the LH side grille for clearance to the hood latch though as other reviews mention. It looks like the design has been revised to address that problem. I was impressed with the paint finish and there weren't any noticeable blemishes like dust or dirt in the paint. These are probably the best and cheapest gloss black kidney grilles for E46 that are currently available. OEM grilles w/ gloss black are basically discontinued so we're all stuck with aftermarket if you want the gloss black shadowline look.

loose fitment
Size: 2002-2005 E46
I guess it's a hit or miss with this. You either get perfect fitment or poor fitment like I did, after the install it's very loose.

Awful fitment, poor quality
Size: 2002-2005 E46
Although not oem quality was expected, but I never thought to throw them away either. Grills look very nice, outside quality is good. Unfortunately the grills do not fit to its place and slip just after you close the hood. After several tries to make them stay in place I have broken 2 clamps. Finally I have removed these grills and went on with OEM ones. Also, pay attention that you must drill a space for hood lock on the inner side (driver side grill does not have the factory space for hood lock handle).
