Efoy Battery Charger

Once tried, never forgotten: with the EFOY Comfort Fuel Cells from SFC Energy installed on board, you can look forward to years of fully autonomous, maintenance-free power supplies for full batteries without any need for intervention on the part of the user. Boat owners have been using EFOY Comfort Fuel Cells to provide reliable electricity far from the hubbub of harbors, and more and more racing boats are choosing the lightweight, quiet power supplies from SFC Energy to deliver reliability and success.


EFOY Comfort 140i Methanol Fuel Cell – Power 140 Ah/Day 151 000 211

The fully automatic EFOY Comfort 140i supplies the on-board battery bank with up to 140Ah per day.

The integrated charge controller permanently monitors the charge level of the 12V battery.  This battery starts automatically and switches off again once is charged.

The EFOY Comfort 140i

Is suited for battery banks between 80 and 250 Ah in size and is EFOY’s most popular size.

The EFOY Comfort 140i is optimized to operate less than 120 days per year, typically during the spring, summer and autumn months.

It meets the typical energy needs of an Inverter <1000 W, lights, TV, chargers, and possibly a coffee machine or hairdryer.

Your batteries will last a lot longer because constant recharging protects them against a damaging exhaustive discharge.

The EFOY Comfort 140i

produces electricity using the fuel in the fuel cartridge, adding oxygen from the air.

In addition to the electricity, it only produces waste heat and water vapour containing an insignificant amount of carbon dioxide.

It is extremely eco-friendly, quiet, and can be installed inside the cabin with no maintenance required.

The high-quality and user-friendly Operating Panel is installed inside your boat. With it, you will find all the key information clearly arranged, even the fuel cartridge’s fill level.

It is simplicity at its best.

Over the period of one year, EFOY Comfort provides 3 to 10 times as much electricity as a solar system with the same power rating.

Every EFOY fuel cell employs DMFC (Direct Methanol Fuel Cell) technology, which transforms methanol directly into electrical current. That’s a real advantage, especially for mobile applications, because liquid methanol is easy to transport anywhere in safe, practical EFOY fuel cartridges.

An EFOY Fuel Cell is an alternative energy source, transforming chemical energy into electrical energy with no intermediate steps, no moving parts, and no significant loss in energy, making it a particularly efficient source of power.

Many patented innovations have gone into SFC Energy AG’s EFOY units, making the EFOY fuel cell a marvel of miniaturization, a lightweight but high-powered, long-lasting performer.

EFOY’s home-grown technology has positioned EFOY fuel cells to lead the field in fuel-cell systems for mobile applications.

At the heart of every EFOY fuel cell is the Stack. A Stack actually consists of several cells: an anode, a cathode, and a membrane that acts as an electrolyte, separating the anode and the cathode from each other.

Positively charged electrical particles (protons) can permeate the membrane.

Methanol and water are introduced on the anode side while ambient oxygen enters the cathode side. H+ ions, free electrons and carbon dioxide arise on the anode side.

The protons can permeate the membrane while the electrons have to travel an electrical circuit over to the cathode side, thereby producing an electrical current. H+ ions and water vapour arise on the cathode side, making EFOY fuel cells an extremely environmentally friendly way to generate electricity.
