<p style="-webkit-font-smoothing: antialiased; display: inline; margin: 0px; color: #111111; font-family: Lora, 'Palatino Linotype', 'Book Antiqua', 'New York', 'DejaVu serif', serif; font-size: 19.2px; white-space-collapse: preserve;">A fuel cell engine operates on the principle of converting chemical energy into electrical energy without combustion. The core component is the fuel cell stack, which consists of multiple individual fuel cells. Here&rsquo;s a breakdown of the process:



<ol style="margin: 2rem 0px -1rem; color: #111111; font-family: Lora, 'Palatino Linotype', 'Book Antiqua', 'New York', 'DejaVu serif', serif; font-size: 19.2px; white-space-collapse: preserve;">
<li style="line-height: 1.5; margin-top: -0.5rem; margin-bottom: -0.5rem;">
<p style="-webkit-font-smoothing: antialiased; display: inline; margin: 0px;">Hydrogen Supply &ndash; Compressed hydrogen gas is stored in high-pressure tanks and fed into the anode side of the fuel cell.

</li>
<li style="line-height: 1.5; margin-top: -0.5rem; margin-bottom: -0.5rem;">
<p style="-webkit-font-smoothing: antialiased; display: inline; margin: 0px;">Electrochemical Reaction &ndash; At the anode, hydrogen molecules are split into protons and electrons. The protons pass through an electrolyte membrane, while the electrons travel through an external circuit, generating electricity.

</li>
<li style="line-height: 1.5; margin-top: -0.5rem; margin-bottom: -0.5rem;">
<p style="-webkit-font-smoothing: antialiased; display: inline; margin: 0px;">Oxygen Intake &ndash; Ambient air is supplied to the cathode, where oxygen molecules combine with protons and electrons to form water.

</li>
<li style="line-height: 1.5; margin-top: -0.5rem; margin-bottom: -0.5rem;">
<p style="-webkit-font-smoothing: antialiased; display: inline; margin: 0px;">Power Generation &ndash; The electricity produced drives an electric motor, propelling the vehicle or powering other applications.

</li>
</ol>
