- Additional information
- This study represented the first application of electrochemical impedance spectroscopy for the characterisation of dynamic anode flooding within an operating PEM fuel cell. This ‘reconstructed impedance’ technique has subsequently been used extensively to monitor similar processes in PEMFCs, including to optimise the purge rate of Intelligent Energy’s (IE) commercial air-cooled fuel cell stacks, resulting in a 5% improvement in fuel efficiency (simon.foster@intelligent-energy.com).
