Biography:
Dr. Juda's track record includes founding, and then harvesting, two businesses operating worldwide: Ionics, involved in electrodialysis equipment for water desalination using proprietary ion-exchange membranes, as well as Prototech Company, involved in pollution control using proprietary catalysts and patented noble metal chemistry, where he is Board Chairman (retired). His current venture is the development of proprietary components (protected by patents both in the U.S. and abroad) to generate pure hydrogen, reliably, at a much lower cost. The hydrogen purifiers and small hydrogen generator systems are being sold to laboratories and chromatographers. This new equipment will supply pure hydrogen to PEM fuel cells for eventual use in residential power generators. Dr. Walter Juda is the inventor of the original ion-exchange process for desalting brackish ground and sea water as well as a number of other electrochemical processes. Currently, he cooperates with Prof. Jerry Meldon on research related to the absorption and permeability of hydrogen in metals like palladium.

Professional Projects:
As Executive V.P. of Ionics and as President of Prototech, Dr. Juda had direct supervision over the proprietary development of products and applied research. Prototech's staff possessed experience and capabilities in the general area of physical chemistry and in particular, electrochemistry, including the following: energy conversion with emphasis on fuel cells and other means of converting chemical energy into electrical energy; molten salts; catalytic oxidation of air contaminants; and fire retardant coatings. Prior to 1990 the independent company developed and patented products with the primary goal of licensing these products to others with those who market inventions. Since Prototech's conversion to a catalyst manufacturing company in 1990, Dr. Juda divides his activities as Board Chairman, between administration, financial planning and long-range technical research and development of the catalyst market.

Honors & Societies:

• Chairman of Gordon Research Conference on Ion Exchange, 1953
• John Price Wetherill Medal of the Franklin Institute (for his development of a commercial method of desalting saline water by electrodialysis), 1960
• American Chemical Society; Association of Harvard Chemists; Sigma Xi.
