====Summary====                   
{{$demo.summary}}



====Procedure====  
  - Assemble the commercially available hydrogen fuel cell kit according to instructions.  
  - Fill the kit’s water reservoirs with distilled water.  
  - Connect the electrolyzer section to a low-voltage power supply (such as a small solar panel or battery).  
  - Allow the electrolyzer to run until hydrogen and oxygen gases are visibly collected in their respective chambers.  
  - Disconnect the power supply and connect the fuel cell to a small load, such as the motor or LED provided in the kit.  
  - Observe how the stored hydrogen and oxygen recombine inside the fuel cell to produce electricity and power the device.

====Variations====
  * Use a solar panel instead of a battery to power the electrolysis, demonstrating renewable energy integration.  
  * Connect different loads (small fan, LED light, buzzer) to see how much energy the fuel cell can provide.  
  * Collect measurements of voltage and current during both electrolysis and fuel cell operation for more advanced analysis.



====Safety Precautions====
  * Use only distilled water to prevent mineral buildup in the apparatus.  
  * Do not attempt to ignite the hydrogen gas produced; it is highly flammable.  
  * Follow manufacturer’s instructions carefully to avoid damaging the kit.  
  * Ensure the apparatus is used in a well-ventilated area.




====Questions to Consider====
  * What are the products of electrolysis of water? (Hydrogen and oxygen gases.)  
  * What reaction occurs when the fuel cell produces electricity? (Hydrogen and oxygen recombine to form water, releasing energy.)  
  * Why is hydrogen considered a clean fuel? (Its only combustion or fuel cell byproduct is water.)  
  * How could fuel cells be useful for future energy systems? (They can store renewable energy, power vehicles, and reduce carbon emissions.)  
  * What limits the widespread use of hydrogen fuel cells today? (Storage and transport challenges, cost of infrastructure, and efficiency of hydrogen production.)
