ABSTRACT
This paper deals with the electrochemical production of hydrogen by depolarizing the oxygen evolution reaction using human feces and urine, which contains 30-40% bacteria and yeast. The electroactivity of graphite, tungsten carbide, perovskite and RuO2-coated Ebonex (Ti4O7) as anode materials are compared. The scale-up of the process in a laboratory-scale three-dimensional packed bed cell is discussed.

This paper discusses the structure of adsorbed water at interfaces. It begins with a review of the development of the research, then examines and compares some of the most important models in this field. The results of recent spectroscopic work, especially those of IR spectroscopy, are discussed and applied to the selection of the most probable model.
