The HYDROMAX 150 is a fuel cell battery charger – a quiet and reliable means of producing 12V power, anytime and anywhere.
What will it do for me?
Help you achieve an energy neutral boat
This is desirable for many cruisers… but it’s not always easy. It’s amazing how power demands can escalate – perhaps there’s not enough sun or wind, you’ve been sitting at anchor for days, you want to make water or run your fridge, or you have friends on board with more iPads and iPhones to charge!
The Hydromax 150 is easy, safe, quiet, and won’t generate excessive heat. You won’t have to maintain it (other than refilling the Fuel and Additive tanks), it is environmentally friendly, and best of all – it’s on-demand power (anytime, anywhere) so your batteries will never draw down too low.
Monitor battery voltage
Not only that, but the HYDROMAX’s integrated voltage regulator will monitor your battery voltage, so you will have one less thing to worry about.
How does it work?
The HYDROMAX 150 uses breakthrough Fuel Cell technology. It’s an eco-friendly power supply – for wherever your boat takes you. Irrespective of the weather and even at sub-zero temperatures, the HYDROMAX 150 converts the solutions in two tanks directly into electrical current using the in-built Fuel Cell.
You never need to open the unit (in fact, that will void the warranty) so in order for it to work for you, all you need to do is hook up the two tanks of solution and a waste line, and connect the system to your 12V batteries.
What’s happening inside?
The mixing of the two water-based solutions – a salt (we call it the Hydrofuel) and an acid (the Additive, aka malic acid) – provide a chemical reaction that produces Hydrogen gas. The Hydrogen molecules are then split by a catalytic converter and this process produces electrons. The electrons flow through an electric circuit and this is the electric current which can be used! Finally, the split hydrogen molecules come into contact with oxygen (O2) and water (H2O) is created.
After the Hydromax has been used, a washing cycle automatically cleans the unit and pumps out the waste product (the water and a small amount of malic acid).
Anode: H2 → 2H + + 2e- Cathode: O2 + 4H + + 4e-→ 2H2O
Whole cell: 2H2 + O2 → 2H2O + energy (electricity and heat)
Hydromax 150 IS UNIQUE
- It uses no flammable fuel
- The mixing of two very safe solutions – a salt and an acid (malic acid, which is found in fruit and used as a food additive) – provides the chemical reaction
- These fuels are shipped and stored in dried powder form
- Can produce 300 Amps in a 24 Hour period

A Sail Magazine Annual Award
Fuel cells were used in early spacecraft because of their relatively light weight and the fact that they produce water as a “waste” product. They have since come down to earth and more recently moved out on the water, where they’ve been used in specialized applications, such as aboard Mini Transat racers.
For years they have been impractical for ordinary sailors because they require compressed hydrogen or methanol for fuel, both of which are heavy to store and highly inflammable.
However, this new Hydromax 150 fuel cell from the Dutch company Dynad uses fuel that can be safely transported in powder form—specifically, a mixture of malic acid (found in apples) and a saline solution—which produces the hydrogen needed to power the unit. Available in 12- or 24-volt models, the Hydromax 150 measures just 7.5 x 16 x 10.5in, weighs 20lb and is rated for 180 watts output. Though expensive, it is still only half the price of its principal competition and boasts 50 percent higher output.
