AquaCure vs Dedicated Hydrogen Inhalation Machines
Both approaches generate hydrogen for inhalation, but they use different engineering methods. This is a factual, manufacturer-neutral comparison of alkaline electrolysis (as used by AquaCure) and PEM electrolysis (as used across the Hydrogen Machines dedicated inhaler range).
Specifications at a glance
| AquaCure (alkaline electrolysis) | Dedicated PEM hydrogen inhalation machines | |
|---|---|---|
| Electrolysis principle | Alkaline electrolysis | PEM (Proton Exchange Membrane) electrolysis |
| Electrolyte system | Aqueous electrolyte solution, commonly potassium hydroxide (KOH) | Solid polymer membrane — no liquid electrolyte |
| Membrane / separator | Diaphragm or microporous separator between electrodes | Solid perfluorosulfonic-acid polymer membrane |
| Water requirements | Distilled water plus periodic electrolyte top-up per manufacturer instructions | Distilled or RO water only |
| Routine consumables | Electrolyte (e.g. KOH pellets / solution), per manufacturer schedule | No liquid electrolyte; periodic membrane rinse cycle |
| Typical maintenance | Electrolyte handling, periodic refresh, follow manufacturer PPE and disposal guidance | Distilled water refill, periodic rinse cycle, no electrolyte handling |
| System architecture | Single combined output stream (some models) or separated streams depending on design | Separated H₂ and O₂ streams; H₂ delivered to cannula or mask |
| Form factor | Bench-top countertop unit | Bench-top or floor units across a defined range of outputs |
| Typical use environment | Home use; some practitioner use | Home, professional, clinic and multi-user installations |
| Certification examples | Per manufacturer's published documentation | CE, FCC, RoHS; manufactured under ISO 9001 / ISO 13485 quality systems |

Key similarities
- Both generate hydrogen on demand from water using electrolysis.
- Both are intended for inhalation use via a delivery accessory.
- Both can produce high-purity hydrogen when correctly designed and maintained.
- Both require following the manufacturer's water-quality, maintenance and safety instructions.
Key differences
- Alkaline electrolysers commonly use a liquid electrolyte (e.g. KOH); PEM electrolysers use a solid polymer membrane and no liquid electrolyte.
- Routine consumables differ: electrolyte refresh (alkaline) vs membrane rinse and distilled-water refill (PEM).
- System architecture and gas-handling differ between the two approaches.
- Product ranges differ: AquaCure is a single product; dedicated PEM inhaler ranges (such as Hydrogen Machines') span multiple output classes for home, professional and clinical use.
Which one fits you?
Buyers who prefer a single-unit alkaline platform and are comfortable with electrolyte handling, periodic electrolyte refresh and following the manufacturer's maintenance and PPE guidance.
Buyers who prefer no liquid electrolyte, distilled-water-only operation, a choice of output classes (900 / 1200 / 1800 / 3000 ml/min and above), and platforms intended from the outset for hydrogen inhalation.
PEM inhalers in the Hydrogen Machines range carry CE, FCC and RoHS certifications and are manufactured under ISO 9001 and ISO 13485 quality systems. Certifications describe hardware, electrical safety and manufacturing — not therapeutic status. For AquaCure, refer to the manufacturer's published certifications and documentation.
View all certifications →Alkaline systems require periodic electrolyte management per the manufacturer's schedule, including correct handling, PPE and disposal of used electrolyte. PEM systems require distilled or RO water and a periodic rinse cycle; no liquid electrolyte is involved. In both cases always follow the manufacturer's published maintenance instructions.
Frequently asked questions
- What is alkaline electrolysis?
- Alkaline electrolysis splits water into hydrogen and oxygen using an aqueous electrolyte solution — most commonly potassium hydroxide (KOH) — to conduct ions between two electrodes separated by a diaphragm or microporous separator. It is a long-established industrial electrolysis technology.
- What is PEM electrolysis?
- PEM (Proton Exchange Membrane) electrolysis uses a solid polymer membrane — typically a perfluorosulfonic-acid material — to conduct protons between electrodes. No liquid electrolyte is required; the cell runs on distilled or RO water.
- Why do alkaline electrolysers use potassium hydroxide?
- KOH increases the ionic conductivity of the water in the cell, allowing efficient electrolysis at moderate voltages. It is a standard electrolyte choice for alkaline electrolysis. KOH is a strong base, so manufacturers specify handling, PPE and refresh procedures for safe use.
- How does PEM technology differ?
- The solid polymer membrane both conducts protons and physically separates the H₂ and O₂ streams. There is no liquid electrolyte to top up or refresh, the cell can start and stop quickly, and the H₂ stream is delivered directly to the user accessory.
- What maintenance is required?
- For alkaline systems: distilled-water top-ups, periodic electrolyte refresh per the manufacturer's schedule, and correct electrolyte handling and disposal. For PEM systems: distilled or RO water refills and a periodic rinse cycle. Always follow the manufacturer's published maintenance instructions.
- What questions should buyers ask before purchasing?
- Ask about published specifications (flow rate, purity, certifications), water requirements, routine maintenance and consumables, warranty terms, available output classes for your intended use, and support and parts availability in your region.
