Hydrogen fuel cell technology has become a huge part of many companies’ goals to reduce their carbon emissions. Fuel cells can be adapted to power many different applications such as automotive, aviation, material handling, and energy storage. An important component of fuel cells, much like a gas engine, is that it has a coolant loop to keep it protected. Excess ionic charges in a fuel cell’s coolant loop can damage an engine, that is why it is so important to utilize a deionizing fuel cell filtration system. De-ionizing filtration systems, like the PROTECT+ion Omniflow, work by using resin to deionize the coolant. Ion exchange is a reversible chemical reaction where an ion from wastewater solution is exchanged for a similarly charged ion attached to an immobile solid particle (such as the resin).

Ion exchange resins consist of small, microporous beads that are insoluble in water and organic solvents. The most widely used base materials are polystyrene and polyacrylate. The beads remove the ionic charges in the coolant so that they cannot damage the fuel cell. The nuclear-grade resin inside of the PROTECT+ion Omniflow is designed specifically for use in nuclear loops where the highest resin purity and stability are required. Our resin is the resin of choice for applications that demand the highest effluent purity, highest operating capacity, and longest resin life. Even though the resin inside of the PROTECT+ion Omniflow is the best-performing resin for fuel cell applications it becomes exhausted over time which is why it is important to replace it to keep your application performing at its best.

As coolant flows through the filter it goes through the path of least resistance. In many filters, this would wear down the resin in one spot and not utilize all of it. The PROTECT+ion Omniflow filter has been designed with a patented internal lattice structure to direct the flow of coolant so that the resin is evenly used. This structure prolongs the resin life inside of the filter compared to similar filtration devices.

“Over time positive and negative contaminants in the water displace the active hydrogen and hydroxyl molecules in the ion exchange resin and the resin loses its ability to remove contaminants, it becomes exhausted.” (Aquaticlife). When this happens, the resin needs to be replaced to keep your fuel cell application protected. Knowing the lifespan of the resin in your filter is important for staying ahead of potential damage.

The PROTECT+ion Omniflow filter maintains a low conductivity level in the fuel cell coolant loop. Pumps, fittings, hoses, heat exchangers, etc. slowly release ions into the coolant which eventually exhausts the resin. It is important to determine the accurate filter life in your specific application so a new PROTECT+ion Omniflow filter can be installed before any fuel cell damage occurs.

The best way to determine the PROTECT+ion Omniflow change interval is to test a filter that has been installed and run for a significant number of operating hours. i2M can test the used filter for remaining ion exchange capacity which will then allow an accurate total filter life to be calculated. We will send you the lab report so that you can understand the filter life for your application and keep it protected from future damage.

As hydrogen fuel cell technology advances, we will see many different sectors adapt the technology in order to reduce carbon emissions. The PROTECT+ion Omniflow has been designed to fit into a variety of fuel cell applications at any orientation and is available in four different sizes. Ensure that your fuel cell is protected at all times by knowing the remaining life of your resin with i2M’s free lab testing. Contact us today at (919)-819-1978 or online at www.i-2-m.com.
