A thermochemical two-step water-splitting cycle using a redox system of iron-based oxides or ferrites is one of the promising processes for converting solar energy into clean hydrogen in sunbelt regions. An iron-containing yttrium-stabilized zirconia (YSZ) or Fe-YSZ is a promising working redox material for the two-step water-splitting cycle. -YSZ is formed by a high-temperature reaction between YSZ and supported on the YSZ at in an inert atmosphere. -YSZ reacts with steam and generates hydrogen at to form -YSZ that is reactivated by thermal reduction in a separate step at temperatures above under an inert atmosphere. In the present study, ceramic foam coated with Fe-YSZ particles is examined as the thermochemical water-splitting device to be used in a solar directly irradiated receiver/reactor system. The Fe-YSZ particles were coated on an Mg-partially stabilized zirconia foam disk, and the foam device was tested during the two-step water-splitting cycle; this was performed alternately at temperatures between and . The foam device was irradiated by concentrated visible light from a sun simulator at a peak flux density of and an average flux density of (total power input on the surface of the foam was 0.296 kW) in a gas stream; subsequently, it was reacted with steam at while heating by an infrared furnace. Hydrogen successfully continued to be produced in the repeated cycles.
