Fuel cells as a clean & efficient power source

Fuel cells are indeed remarkable electrochemical devices that play a pivotal role in generating electricity through the interaction of a fuel and an oxidizing agent, commonly oxygen or air. They are celebrated for their clean and efficient conversion of chemical energy into electrical power, with minimal emissions. This quality renders them highly valuable for a diverse array of applications spanning power generation, transportation, and portable electronics.

One of the key attributes that sets fuel cells apart is their impressive energy density. In comparison to batteries, which typically range from 0.1 to 0.27 kWh/kg, fuel cells, particularly hydrogen fuel cells, offer substantially higher energy density. For instance, hydrogen gas, a common fuel for these cells when stored at 700 bars pressure, boasts a remarkable energy density of 39.6 kWh/kg. This characteristic underscores the immense potential of fuel cells in applications where extended operation and high energy storage are paramount.

Fuel cells come in various types based on the electrolyte they employ, including alkaline fuel cells (AFC), proton exchange membrane (PEM) fuel cells, and solid oxide fuel cells (SOFCs), each catering to distinct applications and operating conditions.

At present, our focus is dedicated to the development of cost-effective electrodes engineered to deliver exceptional performance in fuel cell applications. This work holds the promise of advancing the efficiency and sustainability of fuel cell technology, contributing to a cleaner and more energy-efficient future.
