To find a method to increase the output of the iron-thionine photogalvanic cell, experimental and theoretical research regarding a new type of cell with flow-through electrodes was carried out. The electrode-active species, leucothionine, is deactivated by the reaction of ferric ion and its own. If the active species reaches the electrode surface before its deactivation, an increase in output is expected. In the new system, leucothionine is produced in the illumination zone and transported to flow-through electrodes of carbon fiber felt by the flow of the solution.
The conversion efficiency of light intensity to electric power reached 0.236% at the maximum value. A theoretical analysis was then made of the mixed potentials of thionine and iron redox couples by using a two-phase model of the porous electrode.
