The Salt-water Fuel Cell Science Kit illustrates a cutting edge fuel cell concept: combine a saltwater electrolyte with magnesium plates to generate electrical energy. The Salt Water Fuel cell kit enables you to investigate the science behind salt water fuel cell technology, either by powering the included mini-turbine or creating your own power applications.

  • Features magnesium salt-water fuel cell power device
  • Develop your own micro-fuel cell applications
  • Easy to integrate and use
  • Compatible with other Horizon science kits
  • Create energy from salt water solution and power a fan
  • Analyze current and voltage variation using different salt concentrations
  • Analyze current and voltage variations using different temperatures
  • Analyze current and voltage variations using different fuel volumes

What is a salt water fuel cell? How does it work?

This kind of fuel cell works with air and with a plate made with magnesium. The electricity is made by two chemical reactions which occur in two different point of the cell. The first sight of the reaction is on the plate which is called anode. On this side, the water reacts with the magnesium and creates hydrogen ions (protons) and magnesium hydroxide and generates two free electrons. On the other part of the cell (cathode), the oxygen contained in the air which pass through the cell walls react with the water in order to constitute hydroxide ions. This reaction is possible only if there are additional electrons which are provided. So during the reaction, the free protons generated on the anode are attracted by the cathode because of the difference of potential. If the cell is linked to an electrical circuit, the free electrons will pass inside it in order to reach the cathode and let the second reaction happen. You can find the two half redox equations below.

Mg + 2H2O → Mg(OH)2 + 2H + 2e-

1/2 O2 + H2O + 2e- → 2OH

2Mg + O2 + H2O → Mg(OH)2

The salt in the water is used as a catalyst. In other words, it means that salt accelerate the reaction between Mg and water.

What Educators are Saying About Geyer

Justin has been nothing but helpful and professional in my requests for these Boeing Defense requirements. He has been able to answer my questions and concerns quickly, and helped in securing the order that I may have made with another supplier had be not been the value-add that he is to your company. I hope his merit raise this FY was "exceeds expectations".

Jesse C.

..I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!

John C.

The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.

Robert C.

I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.

Mischelle F.

...I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
