Abstract
The present invention is directed to a photolytic cell, and to a photolytic artificial lung incorporating such a cell. The photolytic artificial lung converts water to oxygen for blood absorption, regulates pH, the removes carbon dioxide, and co-produces electrical power. The photolytic artificial lung includes a photolytic cell where all of the chemical reactions occur. Additionally, the present invention relates to photolytically sensitive materials for oxygen generation. These materials are useful for gas-free artificial lung fabrication. The photolytic cell disclosed herein can also be used to direct chemical reactions in organs other than the lung. It can also be used to maintain breathing air in confined systems.
