Publikováno v: Proceedings of the 15th International Heat Transfer Conference.

The direct conversion of solar energy and water into a storable fuel via integrated photoelectrochemical (PEC) devices is investigated. Particularly, the proposed device uses concentrated solar irradiation in order to minimize the amount of rare and

This paper presents a numerical model for fuel cells and electrolysis cells that use cermets as electrodes. The mass and charge continuity equations were demonstrated inside the electrodes and in the divergence term, surface ratios were used instead

Publikováno v: ECS Meeting Abstracts. :597-597

The photoelectrochemical (PEC) production of hydrogen offers a direct pathway for the conversion of solar energy into an energy dense and transportable fuel. In an integrated PEC device, solar radiation is absorbed by photoactive components which pro
