GTI performs research on high-temperature (molten carbonate and solid oxide) fuel cells. Our laboratories include all the materials processing, fabrication, and testing equipment necessary for fabricating related components.

We also perform research on low-temperature proton exchange membrane (PEM), direct methanol, and alkaline fuel cell power systems. We have extensive experience making and testing fuel cell stacks through a vertically integrated in-house stack prototyping process, and we have also developed specialty systems such as bio fuel cells.

Our expansive testing facilities house multiple fuel cell test stations to test single cells and components, two stations for multi-cell stacks up to 5 kW, and one 12 kW test station; and fuel processor test bays that allow operational testing of prototypes from 50 watts to 25 kW capacities.

In addition, we have test stations for the evaluation of new catalyst formulations over a wide range of operating conditions with electrochemical instruments, FTIR, high temperature/high pressure TGA, a high-resolution microscope, and several high-temperature ovens. Vibro-mill and ball-mill systems are used to develop nano-size particles.​


GTI has the equipment and expertise to develop a variety of membranes, such as organic polymer membrane, zeolite membrane, metal alloy membrane, high temperature ceramic membrane, and combination membranes. We have a strong focus on high-performance and low-cost materials, looking particularly at gas and water purification membranes, membranes for hydrogen clean-up and purification, as well as methane storage.

We have extensive investments in fabrication equipment including casting machines and lines; calenders; ovens; screen printing; and coating equipment for membrane production. We have an automatic continuous conveying system for pilot production and can scale up for material production. We also provide materials testing services to outside organizations.​


GTI has extensive facilities for working with high-pressure, cryogenic, and other novel combustible energy sources, including compressed hydrogen (up to 14,000 psig). We are able to design a variety of testing platforms to meet specific customer needs.

Our hydrogen storage laboratory has three advanced Sievert test systems coupled with a dynamic high-temperature/high-pressure TGA to obtain precise hydrogen storage capacities of materials of interest.

We offer a unique facility for conducting controlled testing, data collection, and evaluation of technolo-gies and products under a range of temperature conditions in a Class I, Division 2 electrically classified test lab that can be modified for specialized testing of combustible gases.

The large-scale environmental chamber (3,000 ft3) can be used for controlled and extreme temperature testing programs. It has a range of precision instrumentation including pressure transmitters, temperature measurement devices, and flow meters that is networked into a high-speed data acquisition system to capture multiple channels of information.

The environmental chamber includes a full-size hydrogen high-pressure cascade storage system. Hydrogen production, purification, and compression equipment capable of providing high pressure gaseous hydrogen for testing at fuel-cell quality purity and up to 14,000 psig is available.

Development of materials for hydrogen storage and storage using adsorbed natural gas (ANG) technology to lower the cost of light-duty hydrogen fuel cell or natural gas vehicles are also primary areas of effort at GTI.​


GTI has expertise in developing membranes for water purification. Our water treatment laboratory has four test units to treat diverse water sources, such as brackish water, seawater, and well water. Analytical tools, such as HPLC and GC, are coupled with the units.​
