Where Energy Meets Environment
Solid Oxide Fuel Cells
Nexceris has a rich heritage in solid oxide fuel cell (SOFC) technology development, and has established itself as a world leader in the field. Starting in the mid 1990’s, the initial focus of Nexceris on SOFC materials and components led to the launch and growth of fuelcellmaterials in 2000. Nexceris engineers have applied their ceramic materials skills to the fabrication of all types of SOFCs – planar and tubular, anode-supported, electrolyte-supported, and inert-supported configurations. This experience enabled Nexceris to better understand technical issues being experienced by SOFC developers and to develop unique solutions to address these issues and to improve the quality and scope of fuelcellmaterials products, including the ChromLok™ and AlumiLok™ lines of corrosion-protective coatings.
Nexceris initiated its SOFC stack technology development work in 2006, following their development of novel electrolyte supported planar cell designs (now patented) with enabling attributes. These cell designs feature a thin electrolyte membrane layer that enables high performance and a dense cell periphery that provides an optimum sealing surface. Nexceris has focused its SOFC stack development work on military applications where high power density, high efficiency, system simplicity and fuel flexibility are desired. A key Nexceris accomplishment was the development of anode technology with unprecedented tolerance to sulfur, which provides a path for SOFC operation on JP-8 fuels without desulfurization. Another important attribute of the Nexceris stack technology is the ability to operate at high single-pass fuel utilization – this greatly simplifies the system design. Examples of recent and ongoing Nexceris SOFC stack technology development include:
Lithium Ion Batteries
Nexceris is developing a new product designed to make advanced lithium ion battery systems safer and more reliable. The risk of explosion due to defective or damaged batteries has led to an increasing need for fast and reliable detectors capable of monitoring the health of these battery systems. Sensor technology exists today that can detect electrical and temperature changes in lithium-ion battery cells that are indicators of a potential safety threat. However, they do not provide enough diagnostic information to prevent catastrophic failure in some circumstances. Nexceris has developed new sensor technology, aimed at adding additional layers of information to improve monitoring the health of lithium ion battery systems. Unlike traditional battery health monitoring methods, the Nexceris technology does not require installation at the individual cell level, but can be installed to measure battery packs or system enclosures, significantly reducing cost and simplifying implementation.
Hydrogen Fuel Cells
Fuel cells are used in a rapidly growing number of primary and back-up power applications, including forklift trucks, cars, buses, homes, and businesses. Detection of hydrogen leaks is essential to the safe implementation of these systems.
Nexceris has developed hydrogen sensors, which are commercially available through its NTM Sensors brand. Integration of our NTM SenseH2® hydrogen sensor in fuel cell systems provides real time monitoring and rapid detection capability of potential hydrogen leaks before flammable levels are reached. Moreover, installation of the NTM Hydrogen alarm system can provide safety monitoring at hydrogen filling stations or near hydrogen storage containers.
