DEVELOPMENT OF NOVEL PHOTO-FUEL CELLS FOR THE PRODUCTION OF HYDROGEN AND ELECTRICITY VIA OXIDATION OF ORGANIC COMPOUNDS WITH THE USE OF SOLAR RADIATION

Abstract: 

Photo(electro)catalytic processes have attracted significant attention in recent years as promising methods for harvesting and utilization of solar light in environmental and energy-related applications. Although remarkable progress has been made in fundamental research, the practical achievements in the field of solar energy conversion and storage have been modest, mainly due to the low efficiency of photocatalysts under solar irradiation, scale-up problems and lack of compact photoreactor designs.

The principal aim of the proposed project is to develop novel materials and components of an integrated process for the production of electrical energy and/or fuel hydrogen via oxidation/reforming of organic compounds in solution with the use of solar light. This will be achieved with the development of an innovative Photo-Fuel Cell, which integrates the concepts of a photovoltaic cell, of a fuel cell and of a H2 generator. In this cell, photogenerated holes produced at the irradiated photoanode will be used to oxidize organic compounds toward CO2.

Photogenerated electrons will be driven via an external circuit to the (dark) cathode where, depending on the application, they will be used to either:

  • reduce water to hydrogen (H2 generator mode), or
  • reduce molecular oxygen to water (Fuel Cell mode).

An important characteristic of the process is that it utilizes in an efficient manner both the incident light energy and the chemical potential of organic compounds for the production of electricity and/or hydrogen. Target organic compounds that can be used for this purpose include byproducts or surplus of biomass processing industries, wastes, biofuels, etc. It is expected that the proposed process, which runs at ambient conditions, will provide an innovative, efficient, technologically simple, ecologically benign and low cost method for the production of energy with the use of three abundant and renewable resources: solar energy, biomass and water.
