Fuel Cell/Battery Testing

The Greenlight Innovation fuel cell test stations at FCReL are available for both single cell and stack size fuel cell performance and durability testing of fuel cells and redox flow batteries.

The test stations features a 3-way valve for delivery of facility-supplied hydrogen and air via integrated heaters and humidifiers through insulated tubes to the fuel cell stack manifolds.

Micro and Nano X-ray Computed Tomography

Three-dimensional, non-destructive visualization of fuel cells on the micro and nano scales, using a state-of-the-art multi-length scale X-ray computed tomography facility with customized instruments from ZEISS X-ray Microscopy.

Dynamic Mechanical Analysis

The DMA (TA Instruments Q800) equipped with an environmental chamber (TA Instruments DMA-RH accessory) is a state-of-the-art tool to facilitate the in-depth mechanical behavior and durability testing and analysis of fuel cell components.

Utilizing a variety of testing clamps (tension, compression, submersible, 3-point bending, and cantilever) provides the DMA with the capability of conducting a wide range of mechanical and thermo-mechanical testing from dry condition to fully immersed in the liquid water. The DMA testing capabilities are including (but not limited to): Tensile, Compressive, Creep, Stress relaxation, Fatigue-fracture, Hygrothermal swelling and expansion, Glass transition temperature (Tg)

The DMA-RH Accessory allows mechanical properties of a sample to be evaluated under controlled and/or varying conditions of both relative humidity (0-95%) and temperature (ambient-120°C).

Porosimetry

The Greenlight Innovation porosimeter analyzes porous structures with pore sizes from 1nm to 300 micrometers. Using Method of Standard Porosimetery (MSP), it is capable of measuring porosity, pore size distribution, specific surface area, capillary pressure curves, contact angle, and adsorption/desorption isotherms. The MSP also aims to investigate the structure of samples in a working liquid, such as water, methanol and other solvents used in PEM Fuel Cells and in various batteries.

Tensiometry

The force tensiometer measures the forces that are present when a sample of solid is brought into contact with a test liquid. This enables precise characterization of a number of material properties. The tensiometer is capable of the following measurements

  • Dynamic contact angle
  • Surface/interfacial tension
  • Absorption profiles
  • Powder wettability of porous materials, fibers, coatings, and solids

Modeling and Simulation

FCReL has comprehensive capabilities for fuel cell modeling and simulation, including microstructural models, transport property simulations, performance models, and durability models across a wide range of length and time scales
