Dynalene Inc. of Whitehall, Pennsylvania, has completed large scale testing and demonstration of nanoparticle-based fuel cell coolant, and has achieved commercial success in multiple markets. Dynalene’s fuel cell coolant has very low electrical conductivity and uses non-ionic corrosion inhibitors and ion-exchange nanoparticles in a glycol water based solution. By identifying common polymers and metals that provide the best compatibility with a fuel cell at elevated temperatures, Dynalene was able to complete testing of more than 5,000 hours at more than 80 degrees Celsius.

Long-term testing is continuing with several versions of the fuel cell coolants to simulate different applications. In doing so, they are leveraging their knowledge of the intended industries, such as fuel cell cooling, as well as unintended industries like battery cooling, electronics cooling and power generation. Dynalene is currently producing and selling two of the coolants into many of these industries.

The Fuel Cell Technologies Office (FCTO) conducts comprehensive efforts to overcome the technological, economic, and institutional barriers to the widespread commercialization of hydrogen and fuel cells.

The Office of Energy Efficiency and Renewable Energy (EERE) success stories highlight the positive impact of its work with businesses, industry partners, universities, research labs, and other entities.

Project Overview

Positive Impact

Dynalene has been working with several automotive and fuel cell manufacturers on using the coolants in their PEM fuel cells, hybrid electric, electric vehicles and back-up power systems.
