Title: Branko N Popov: Innovator in Fuel Cell Technology

Introduction

Branko N Popov is a distinguished inventor based in Columbia, SC, known for his significant contributions to the field of fuel cell technology. With a total of 7 patents to his name, he has developed innovative methods that enhance the efficiency and cost-effectiveness of polymer electrolyte membrane fuel cells (PEMFCs).

Latest Patents

One of his latest patents involves the development of a novel method for the preparation of PEMFC electrodes. This method utilizes a pulse electrodeposition technique to create membrane electrode assemblies (MEAs). In this approach, platinum is deposited directly onto the surface of the carbon electrode, ensuring that most of the platinum is in close contact with the membrane. This technique allows for an increase in the Pt/C ratio up to 75 wt % near the surface of the electrode, resulting in a catalyst layer that is only 5 µm thick. The MEA prepared by this method exhibits a current density of 0.33 A/cm² at 0.8 V with a platinum loading of 0.25 mg of Pt/cm. The results suggest that pulse deposition could serve as an attractive alternative to conventional powder-type MEA preparation methods, aiding in the reduction of catalyst costs and enhancing efficiency in PEMFCs.

Another notable patent involves a composite electrode for a battery, which includes silver vanadium oxide and polypyrrole. This composite electrode consists of silver vanadium oxide in an amount ranging from about 75 weight percent to about 99 weight percent, and polypyrrole in an amount from about 1 weight percent to about 25 weight percent.
