A water cooling solid breeder blanket is a prime candidate of the blanket of the fusion reactor in Japan. In this case, the blanket tritium recovery system will be composed of three processes: tritium recovery from the helium sweep gas as hydrogen, that as water vapor and tritium recovery from the coolant water. For these processes, the present authors have proposed a set of advanced systems, a...

Solid electrolytes based on oxygen ion conductors find extensive applications as devices for oxygen sensor, oxygen pumps, solid oxide fuel cells and electrocatalytic reactors. When using ceramic ionic conductors for applications, frequent attempts are made to improve the performance of the electrochemical system by apply'rig mixed conductors as thin top layers instead of the conventional ir~ert...

This work proposes the use of electrochemical cells (bipolar or series) like mechanism recuperate of impurities and noble species, from contaminated or impoverished electrolytes. The treated fluid circulates through porous or perforated electrodes of compound material. In order to produce successive, selective deposits of the different chemical substances, these electrodes are located spaced by...

In the present study, the operating conditions of an anode-supported high temperature direct internal reforming (DIR) planar solid oxide fuel cell (SOFC) are numerically analyzed. SOFCs are the energy conversion devices that produce electricity and heat directly from a gaseous fuel by the electrochemical combination of that fuel with an oxidant. A planar SOFC consists of an interconnect structu...

Present address: Xiao-Liang Wang, Seeo, Inc., 3906 Trust Way, Hayward, CA 94545, USA The review presents an overview of the recent advances in inorganic solid lithium ion conductors, which are of great interest as solid electrolytes in all-solid-state lithium batteries. It is focused on two major categories: crystalline electrolytes and glass-based electrolytes. Important systems such as thio-L...

A new type of ozone generator using a micro hollow cathode discharge has been developed. The electrode system consists of two thin metal cathodes and a ceramic spacer with center holes of a few100 mm diameter. The ozone generation efficiency increases up to 45 g/kWh at the ozone concentration of 7.6 g/Nm without any cooling systems by feeding highpressure oxygen. In this ozone generating system...
