EFOY Pro fuel cells

Ideal energy solutions for off-grid and mobile applications. EFOY Pro fuel cells supply power at any time of the year or day.

The technology

The EFOY Pro generates power from fuel methanol in the fuel cartridge, complemented by oxygen from the air. In addition to power, all this creates is waste heat and water vapour with a little carbon dioxide. This is extraordinarily environmentally friendly.

The EFOY Pro models

The EFOY Pro fuel cells are available in various performance categories, with outputs ranging from 45 W for small-scale power systems to a 500 W module for UPS solutions. With a Cluster Controller, multiple devices can also be connected to one battery system. This means that multiple kW outputs can be provided.

1) Nominal power varies by ±10 %, decreases with the operation hours. Specification valid within warranty period.

2) Depends on battery type and application – bigger batteries possible, if additional energy source available (e.g. solar)

3) Regional warranty conditions for EFOY Pro fuel cells apply.

4) Factory Setting – can be modified with Interface Adapter and PC or operating panel OP2.

5) Effective consumption depends on operating conditions.

6) At temperatures above +40 °C / +102 °F the power output can decrease. Charging Lithium (LiFePO4) batteries is not always possible at temperatures below 0 °C. The instructions from the battery manufacturer must be observed.

7) During operation above the recommended altitude the power output can decrease.

EFOY fuel cartridges

Simply adapt the size of your fuel cartridge to your autonomy requirements. They were especially designed to be used with the EFOY fuel cells, and they can be replaced easily and cleanly within seconds.

EFOY fuel cartridges for industry applications are available with 5, 10, 28 or 60 litre capacities. If your autonomy needs are higher, up to four fuel cartridges can be connected to one EFOY Pro Duo fuel cell using the DuoCartSwitch. This means you can autonomously run a 25 W application with four M28 fuel cartridges for up to 30 weeks for example.

In accordance with the CLP regulation, methanol is classified as toxic and flammable substance. Please refer to the safety data sheets for further information.

“Power in any weather”

Previously, we were not able to guarantee a reliable power supply using only solar power. The effort to replace batteries is significant. With the EFOY Pro, we are not only sure that the system has power in any weather but we also save a lot of money by not laying power cables.

Eric Recht, Hydroservices France

Quiet and environmentally friendly

Thanks to environmentally friendly power generation, the EFOY Pro can be used in nature reserves as well as in closed vehicles and rooms.

Fragen und Antworten
zur EFOY Pro

Why do I need an EFOY Pro fuel cell?

The EFOY Pro fuel cell is a fully automated battery charger that is quiet, simple and environmentally friendly, operating as a power generator in regions, where no grid connection is available, but a high power demand is needed. In off-grid industrial applications, that are not connected to the grid, the EFOY Pro fuel cell delivers reliable energy, in every weather condition – for security and surveillance, traffic regulation, remote sensors, etc.

What ist a fuel cell?

A fuel cell is a galvanic cell that converts the energy created by the chemical reaction between a constant stream of fuel and an oxidant into electrical energy. The underlying principle is an electrochemical process that is also known as "cold combustion". It is in principle the reversal of electrolysis. A fuel cell is not an energy store but a converter that generates electricity. The energy required to produce electricity comes from the fuel.

How does the EFOY Pro fuel cell work?

The EFOY Pro fuel cell converts the fuel in the fuel cartridge direct into electrical current. Thanks to this direct conversion, which is performed with no moving parts, silent and environmentally friendly, the fuel cell is extremely efficient, clean and environmentally friendly.
