Fuel cells

A fuel cell is a device that produces electricity by converting chemical energy directly into electrical energy. It works by hydrogen or methanol reacting with oxygen in an electrochemical process that produces electricity, with heat and water vapor as by-products.

Fuel cells are highly efficient and a cleaner source of energy than traditional methods such as diesel generators. They are used in portable devices and off-grid locations that otherwise have no access to the power grid.

Freber supplies complete fuel cell solutions with batteries, inverters, and modems for real-time monitoring. There are box solutions that extend the temperature range to -40°C. The solutions can be scaled from small 40W systems (methanol) up to 50kW containers (hydrogen).

Frequently Asked Questions

What is a fuel cell and how does it work?

A fuel cell produces electricity by converting chemical energy directly into electrical energy through an electrochemical reaction.

Hydrogen or methanol reacts with oxygen to generate electricity, with heat and water vapor as by-products. The process takes place without combustion, resulting in high efficiency and low emissions compared to traditional diesel generators.

When is a fuel cell a better alternative than a diesel generator?

Fuel cells are particularly well suited where the following requirements apply:

Low noise level
Low emissions
High operational reliability
Remote monitoring
Low maintenance

They are often used in off-grid installations, telecommunications, surveillance systems, and locations without access to the power grid.

What solutions does Freber provide?

Freber supplies complete fuel cell solutions that may include:

Fuel cell (hydrogen or methanol)
Battery bank
Inverter
Modem for real-time monitoring
Cabinet solutions for extended temperature range (down to -40 °C)

We scale solutions from small 40 W methanol systems to larger 50 kW hydrogen containers.

Can the systems be customized to our needs?

Yes. We tailor our solutions based on:
