Abstract:
The visual evaluation of fuel cells by conventional means is impossible. To improve the power generation efficiency of fuels cells, the evaluation of catalytic reactions on the electrodes and ion propagation in the electrolyte are important. We developed a terahertz chemical microscope (TCM) to visualize the electric potential shift in the catalytic electrodes of fuel cells. The potential energy shift of the fuel cells due to the dissociation of gases was visualized using TCM during fuel cell operation.
