Title: Innovations by Rajeev Vohra in Fuel Cell Technology

Introduction

Rajeev Vohra is a notable inventor based in Burnaby, Canada, recognized for his contributions to fuel cell technology. With a total of 3 patents, he has made significant advancements in the field, particularly in enhancing the durability and efficiency of electrochemical fuel cells.

Latest Patents

One of his latest patents is a "Method and apparatus for operating an electrochemical fuel cell." This innovative method aims to increase the life expectancy of solid polymer electrolyte fuel cells by reversing the direction of fluid flow after a specific operational time. This time period is strategically chosen to be less than the mean life expectancy of the cell, allowing for multiple reversals throughout the fuel cell's life.

Another significant patent is the "Method for operating fuel cells on impure fuels." This invention addresses the issue of electrocatalyst poisoning caused by impurities in the fuel stream. By introducing a variable concentration of oxygen into the impure fuel stream, Vohra's method can reduce or prevent poisoning without excessive oxygen use. The oxygen concentration can be controlled based on the voltage of a carbon monoxide sensitive sensor cell, making it particularly effective for solid polymer fuel cell systems.
