Fuel Cells

Fuel cells are energy-conversion devices.  Fuel cells will continue to convert their fuel (e.g, Hydrogen) to energy as long as fuel is available.  Common types of fuel cells are Proton Exchange Membrane (PEM) fuel cells, Solid-Oxide fuel cells (SOFC), and direct methanol fuel cells (DMFC).

Each technology has its own techniques.  PEM Fuel Cells use a bipotentiostat, or 2-channel potentiostat, with a rotator and electrodes in a Rotating Ring-Disk Electrode (RRDE) configuration in order to evaluate catalysts used in that reaction-type.  A SECM provides additional high-value information of spatial resolution and the opportunity for matrix-style testing.

SOFC technology uses EIS technique – at both high and low frequency – to identify conductivity.  The drive being to identify oxides that provide sufficient conductivity at a lower temperature.  Validation of this type of system allows higher system efficiency than if the system requires extreme operating temperature.

Princeton Applied Research provides options and ancillary equipment to evaluate PEM fuel cells as well as the ability to be integrated within a larger test system to evaluate the entire device.  Solartron Analytical instrumentation provides the accuracy and frequency range to characterize the new materials in SOFC research.
