Question 1

What is a multi-fuel fuel cell?

Accepted Answer

It is a PEM fuel cell that generates clean electricity from more than one fuel — hydrogen, methanol or ethanol — on a single hardware platform. Lean Eco Cell's patent-pending, single-piece membrane electrode assembly (MEA) makes this possible, so you are not locked into one fuel's logistics.

Question 2

How does a fuel cell compare to a lithium-ion battery?

Accepted Answer

For long-duration use, an LEC multi-fuel fuel cell delivers up to ~15× the power density of lithium-ion at the system level, refuels in seconds, and keeps working from −32 °C to +60 °C where battery capacity collapses. Batteries still suit short bursts and frequent cycling; the two are often paired in a hybrid.

Question 3

Which fuels do LEC fuel cells run on?

Accepted Answer

Hydrogen, methanol and ethanol — on the same platform. Hydrogen offers the cleanest operation where it is supplied; methanol and ethanol are liquid, energy-dense and easy to transport and store, which suits field and off-grid use.

Question 4

What power range do LEC systems cover?

Accepted Answer

The platform is modular from roughly 1 kW to 1 MW, with wearable configurations in the tens of watts. The same architecture scales across the range, so a single technology serves soldier power, UAV packs, portable generators and containerized systems.

Question 5

Are LEC fuel cells suitable for defense and drones?

Accepted Answer

Yes. They run near-silently (under ~40 dB) with a low thermal signature, extend tactical UAV endurance up to ~5.85× versus lithium-ion, and power the dismounted soldier over a ~72-hour mission. LEC provides MIL-STD and STANAG compliance support for defense programs.

Question 6

Is the technology export-controlled?

Accepted Answer

Some end uses (defense, dual-use) fall under EU dual-use regulation (Regulation (EU) 2021/821). As an EU company based in Finland, LEC handles engagements in compliance with applicable export-control and sanctions law; sales into EU/NATO-aligned markets typically have a clear path.

Question 7

How can my company partner with LEC?

Accepted Answer

There are four paths — distribution, system integration, OEM (stack & MEA) and licensing. Submit the short form on the Become a partner page and a member of the team responds within 48 hours to set up a fit call.
