With the global push towards reducing carbon emissions and combating climate change, innovative technologies like Proton Exchange Membrane (PEM) fuel cell stacks are gaining traction for their potential to revolutionize the way we power our world. In this article, we will delve into the role of PEM fuel cell stacks in reducing carbon emissions and their significance in the fight against climate change.
## Introduction to PEM Fuel Cell Stacks
PEM fuel cell stacks are a type of fuel cell that operates at relatively low temperatures, making them ideal for a wide range of applications. These fuel cells use an electrolyte membrane to facilitate the reaction between hydrogen and oxygen, producing electricity, water, and heat as byproducts.
### How PEM Fuel Cell Stacks Work
PEM fuel cell stacks work by splitting hydrogen molecules into protons and electrons at the anode, with the protons passing through the electrolyte membrane to the cathode, while the electrons flow through an external circuit, creating an electric current. At the cathode, the protons, electrons, and oxygen molecules combine to form water and release energy.
#### Benefits of PEM Fuel Cell Stacks
- High efficiency: PEM fuel cell stacks have a high efficiency rate, converting a greater percentage of fuel into usable electricity compared to traditional combustion engines.
- Zero emissions: The only byproducts of PEM fuel cells are water and heat, making them a clean and environmentally friendly energy source.
- Versatility: PEM fuel cell stacks can be used in a wide range of applications, from powering vehicles to providing backup power for buildings.
##### Applications of PEM Fuel Cell Stacks
PEM fuel cell stacks are being used in various industries to reduce carbon emissions and transition to a more sustainable energy future. Some common applications include:
1. Transportation: PEM fuel cell stacks are powering zero-emission vehicles, such as hydrogen fuel cell cars and buses, reducing greenhouse gas emissions from the transportation sector.
