Introduction

The hydrogen fuel cell stands as a beacon of sustainable energy, transforming the chemical energy of hydrogen and oxygen into electrical power with remarkable efficiency. At SHANGHAI WANHOO, we are at the forefront of this technology, harnessing the reverse reaction of water electrolysis to power the future.

The Core Process

The heart of the hydrogen fuel cell is its ability to facilitate a reverse reaction akin to the electrolysis of water. Here’s how it unfolds:

1. Hydrogen Supply: Pure hydrogen gas is introduced to the anode of the fuel cell.

2. Oxygen Introduction: Simultaneously, oxygen, typically sourced from ambient air, is supplied to the cathode.

At the Anode

•  Hydrogen molecules encounter the catalyst, where they are split into protons and electrons.

•  The equation governing this reaction is:

$$ 2H_2 \rightarrow 4H^+ + 4e^- $$

•  Protons pass through the electrolyte membrane to the cathode side.

•  Electrons, however, cannot pass through the membrane. They travel via an external circuit, generating an electric current.

At the Cathode

•  Oxygen molecules react with the incoming protons and electrons to form water.

•  The cathodic reaction can be represented as:

$$ O_2 + 4H^+ + 4e^- \rightarrow 2H_2O $$

The Electrolyte Membrane

•  The electrolyte is the critical component that allows protons to pass while blocking electrons, ensuring the flow of electricity.

The External Circuit

•  As electrons flow through the external circuit, they power any electrical device connected to the fuel cell.

Heat and Water as Byproducts

•  The only byproducts of this process are heat and water, making the hydrogen fuel cell an environmentally friendly power source.
