Lewis Center-based NexTech, formed in 1994, does business in 35 countries and offers more than 100 products, mostly related to ceramic materials used in solid oxide fuel cells. The company is working with a number of partners in development of new products -- and is positioned for growth when more widespread use of fuel cell technology catches on in the U.S. to power vehicles and buildings. Meanwhile, NexTech continues to produce a number of sensors used to detect the presence of gases in the surrounding air. The company in late 2009 began offering hydrogen safety sensors and was working on emissions sensors that it hopes will come to the marketplace in two to three years.
