Electrolysis for Generating Hydrogen: Best Conductor?

[supermancody]

I'm trying to use electrolysis to generate hydrogen. I was wondering, what would be the best material to use for the conductor (the exposed part in the water, which generates the bubbles). I know graphite can be used, but what else that will not contaminate the hydrogen. Thanks!

Platinum is a good choice...

I am glad to hear that you are exploring the use of electrolysis for generating hydrogen. Electrolysis is a well-established method for splitting water into its constituent elements, hydrogen and oxygen, using an electric current.

When it comes to selecting the best material for the conductor in electrolysis, there are a few factors to consider. First and foremost, the material should be a good conductor of electricity. This will ensure that the electric current can flow through it efficiently, leading to a more effective electrolysis process.

In addition to conductivity, it is important to consider the material's compatibility with water. Some metals, such as iron and copper, can react with water and produce unwanted byproducts that could contaminate the hydrogen gas. Therefore, it is best to avoid using these materials as the conductor.

Graphite is a commonly used material for the conductor in electrolysis because it is a good conductor and is not reactive with water. However, there are other materials that can also be used, such as platinum, gold, and silver. These materials are more expensive than graphite but may be a better option in terms of purity and performance.

Ultimately, the best material for the conductor will depend on your specific experimental setup and goals. I would suggest conducting some tests with different materials to determine which one works best for your particular application. Additionally, proper maintenance and cleaning of the conductor can also help prevent contamination and ensure the production of pure hydrogen gas.

I hope this information helps guide your research and experimentation. Good luck with your electrolysis project!
