Oscillation-based Fuel Cell Diagnostics

In this project, we propose two diagnostic tools that can identify dynamical processes in various fuel cell operating regimes, using the difference in the time constant of these processes. For example, conductive transport of electrons is faster than diffusive transport of gasses. We oscillate current and pressure at different frequencies, and measure the cell voltage. We use the amplitude ratio and phase different of these oscillations to detect dynamical processes in the fuel cells. Specifically, we are interested to study water transport in the catalyst pores and hydrogen transfer leak through membrane pinholes using pressure and current oscillations, respectively. These diagnostic tools enable Greenlight to build fuel cell test stations with enhanced capabilities.
