What Is Electrolysis Water?
Electrolysis water refers to water that has been treated using an electrolysis process, where an electric current passes through the water to change its properties. This process splits water (H₂O) into its core elements: hydrogen (H₂) and oxygen (O₂).
Depending on how it’s used, electrolysis water can have different purposes:
- Hydrogen-rich water: When the goal is to infuse water with dissolved hydrogen gas for drinking, improving antioxidant potential, and supporting wellness.
- Alkaline or acidic water: In some systems, electrolysis can adjust the pH of water, creating alkaline water for drinking and mildly acidic water for cleaning or skincare.
- Clean energy generation: On an industrial scale, electrolysis produces pure hydrogen gas used as a green fuel with zero carbon emissions.
The key lies in the electrolyzer or membrane used, high-quality systems (like Dr. Water’s PEM-based devices) ensure clean separation of gasses and safe, high-purity hydrogen infusion without harmful by-products.
How Hydrogen Electrolysis Works?

Water might look calm and simple, but the molecules inside it, two hydrogen atoms bonded to one oxygen atom (H₂O), are held together by strong chemical bonds. Water doesn’t split apart easily, so it needs a little help from electricity. That’s where electrolysis comes in.
The Electrolysis Setup
To understand how electrolysis works, imagine a basic setup with three key parts:
-
Electrodes: These are special metal plates, often made from nickel, platinum, or similar materials, that help the reaction happen faster.
- The anode (+) produces oxygen.
- The cathode (–) produces hydrogen.
- Membrane (or Separator): This thin layer keeps the hydrogen and oxygen gases from mixing while allowing tiny charged particles (ions) to pass through. It ensures both safety and purity.
- Electric Current: Electricity provides the energy needed to pull water molecules apart into hydrogen and oxygen. Without it, nothing happens.
When an electric current passes through the water, it gives energy to the water molecules, causing them to break apart.
Here’s what’s happening in one clear equation:
2H2O→2H2+O2
An electrolyzer is the core device that makes electrolysis possible; it uses electricity to split water into hydrogen and oxygen. Let’s explore the different types of electrolyzers and how each one performs this process in its own way.
Types of Electrolyzers – Different Ways to Split Water
Electrolyzers come in several types, each using a slightly different method to split water into hydrogen and oxygen.
Let’s look at the three main kinds used today:

1. Alkaline Electrolyzer (AEL)
This is the most common and affordable type used in industries. It uses a liquid alkaline solution (like potassium hydroxide) as the electrolyte.
- Durable and long-lasting, perfect for continuous operation.
- Works well for large-scale hydrogen production but reacts slowly to changes in power.
2. PEM Electrolyzer (Proton Exchange Membrane)
PEM electrolyzers use a solid polymer membrane instead of a liquid electrolyte. They’re known for being compact, efficient, and fast to start.
- Ideal for renewable energy setups like solar or wind power.
- Produces high-purity hydrogen and handles power fluctuations easily.
- Commonly used in green hydrogen projects.
3. High-Temperature Electrolyzer (SOEC – Solid Oxide Electrolysis Cell)
This advanced type runs at very high temperatures (around 700–1,000°C). The heat helps make the process more efficient by reducing how much of electricity needed.
- Promises higher efficiency and lower energy use.
- Still in the research and development stage, but it shows great potential for the future of clean hydrogen.
Whether used in massive plants or compact devices, each electrolyzer plays a part in creating a sustainable, hydrogen-powered world.

Why More People Are Turning to Hydrogen Water
More and more people today are looking for something beyond ordinary water. They want hydration that not only quenches thirst but also supports overall wellness, water that feels smarter, cleaner, and more beneficial.
Here’s what they’re looking for:
- Functional hydration: Not just water, but something that may support recovery, energy, or antioxidant balance.
- Effortless wellness: A small, daily upgrade that fits seamlessly into an existing routine.
- Antioxidant and anti-inflammatory support: Hydrogen may help the body combat oxidative stress, one of the root causes of fatigue and cellular aging.
- Faster recovery and better endurance: some studies suggest hydrogen-rich water can reduce muscle soreness and improve post-exercise recovery.
- A smoother, “lighter” taste: users often say hydrogen water feels softer and easier to drink than regular water.
Some people feel a noticeable difference, while others see benefits over time. Scientists continue to study how hydrogen interacts with the body.
Choosing the Right Hydrogen Water Device
Not all hydrogen water generators are created equal. Here’s what to look for when choosing (or recommending) a reliable hydrogen water system:
- PEM Technology (Proton Exchange Membrane) – This is the heart of high-quality hydrogen production. PEM systems separate hydrogen from oxygen and other gasses, ensuring pure, drinkable hydrogen water with no by-products.
- Certified Manufacturing Standards – Look for devices made with BPA-free, food-grade materials and tested for safety and durability. They should produce no harmful residues or ozone.
- Hydrogen Output & Retention – A good generator will specify how much hydrogen (H₂) it produces, usually measured in ppm or ppb, and how long the gas stays dissolved.
- Ease of Use & Maintenance – The ideal device should be simple to fill, start, and clean, with minimal upkeep. Intuitive operation encourages customers to use it daily and enjoy long-term benefits.
- Brand Trust & Transparency – Choose brands that share test results, certifications, and customer reviews openly. Transparent communication builds confidence and loyalty.
When you invest in the right device, you’re not just buying hydrogen water, you’re buying the promise of quality, safety.
