What is fuel cell

A fuel cell is an electrochemical device that generates electricity through a chemical reaction between a fuel and an oxidizing agent, typically oxygen from the air. It is a clean and efficient way to produce electricity, with water and heat as the primary byproducts.

Parts of a fuel cell

A fuel cell consists of several key components that work together to facilitate the electrochemical process of converting fuel into electricity. Here are the main parts of a typical fuel cell:

1. Anode: This is the electrode where the hydrogen fuel is supplied. At the anode, a catalyst helps split hydrogen molecules into protons (H+) and electrons (e-), initiating the electrochemical reaction.
2. Cathode: The cathode is the electrode where oxygen or air is provided. Similar to the anode, a catalyst is used at the cathode to facilitate the reaction where protons and electrons combine with oxygen to form water.
3. Electrolyte: Positioned between the anode and cathode, the electrolyte is a material that conducts positively charged ions (typically protons) while blocking the flow of electrons. It serves to separate the anode and cathode while allowing the movement of ions during the electrochemical process. The type of electrolyte varies depending on the fuel cell type.
4. Catalyst Layers: Catalyst layers are thin coatings of catalyst materials (often platinum) applied to the surfaces of the anode and cathode. They facilitate the electrochemical reactions at these electrodes, reducing the activation energy required for the reactions to occur.
5. Gas Diffusion Layers (GDLs): GDLs are porous materials placed adjacent to the catalyst layers on both the anode and cathode sides. They help distribute the reactant gases (hydrogen and oxygen) evenly across the electrode surfaces and allow the transport of gases and water vapor in and out of the cell.
6. Bipolar Plates: Bipolar plates are typically made of conductive materials like graphite or metal. They provide structural support to the fuel cell stack, serve as electrical connections between individual cells in a stack, and distribute reactants and products throughout the cell.
7. End Plates: End plates are similar to bipolar plates and help compress the individual cells within a fuel cell stack, ensuring proper contact between components and efficient gas distribution.
8. Cooling and Humidification Systems: In some fuel cell designs, cooling systems are integrated to manage the heat generated during the electrochemical reactions. Additionally, humidification systems help maintain the proper moisture level within the fuel cell, optimizing its performance.
9. External Circuit: An external electrical circuit connects the anode and cathode, allowing the flow of electrons generated at the anode to the cathode. This electron flow generates electrical current, which can be utilized for various applications.

These components work together to enable the electrochemical reactions that take place within the fuel cell, ultimately producing electricity, water, and heat as byproducts. The specific design and materials used in each part can vary depending on the type of fuel cell and its intended application.

Fuel Cell Working

A fuel cell operates through an electrochemical process that transforms the chemical energy of a fuel, typically hydrogen, and an oxidizing agent, usually oxygen from the air, into electricity, water, and heat. It consists of an anode and a cathode separated by an electrolyte, which can be a solid, liquid, or polymer membrane.

At the anode, hydrogen fuel is introduced, and through the help of a catalyst, it splits into protons (H+) and electrons (e-). Protons move through the electrolyte to the cathode, creating an ionic current.

Meanwhile, electrons cannot pass through the electrolyte, so they flow through an external electrical circuit, generating electricity. At the cathode, protons and electrons combine with oxygen to produce water vapor and heat.

Cathode Reaction: O₂ + 2H₂O + 4e^– → 4OH^–

Anode Reaction: 2H₂ + 4OH^– → 4H₂O + 4e^–

Net Cell Reaction: 2H₂ + O₂ → 2H₂O
