World's smallest ozone generator
Article Abstract:
Ryoden Kasei reported that it has developed the world's smallest ozone generator, which only requires an input voltage of 3V and can be run by a dry cell battery. Existing ozone generators require an electrical discharge of more than 3 kV. Ryoden's generator is made up of an electrolytic cell whose electrolyte is a solid polymer membrane. Air is pumped through a port into the cell and ozone is produced at the anode from negative OH ions by applying a voltage to the cell.

Fuel cells: generating clean power onsite
Article Abstract:
Fuel cells as a power source for stationary industries, such as the chemical process industry, are being explored for commercialization by the year 2002. The rapid development of fuel cells as power source has been credited to their capacity to provide clean electricity quietly. Its disadvantage is its higher cost compared with other traditional power sources. Molten-carbonate fuel cells and solid-oxide fuel cells are capable of producing a few hundred kilowatts to a few megawatts. Proton-exchange membranes have smaller power production capacity and is ideal for vehicle use.
