Direct methanol fuel cells, such as the EFOY Pro series, depend on a reliable supply of ultra-pure methanol to operate safely and efficiently. For organisations deploying these systems across New Zealand and Australia, fuel logistics are just as critical as the fuel cell hardware itself.
At Powerbox, we stock and distribute a full range of EFOY approved methanol cartridges (M10, M28, and MT60) to support both short-duration mobile deployments and long-term fixed installations.
Global Supply Chain, Local Availability
Powerbox sources methanol cartridges directly from SFC Energy, the German manufacturer of the EFOY Pro. SFC’s certified methanol production and packaging network extends across Germany, Malaysia, and the United States, ensuring continuity of supply and compliance with international transport regulations.
By importing directly from the manufacturer, Powerbox guarantees that every cartridge delivered to our New Zealand clients meets the strict purity and packaging requirements of SFC Energy.
UN Certification and Transport
Methanol cartridges for EFOY fuel cells are classified as dangerous goods (DG Class 3 – Flammable Liquids) and must be packaged, labelled, and shipped in accordance with the United Nations Model Regulations. All EFOY cartridges are UN certified, which means they are approved for air, sea, and land transport globally.
In New Zealand, Powerbox manages the logistics of methanol transport across metro, regional, and remote sites. This includes compliance with road and air freight DG regulations, making methanol supply straightforward for integrators, utilities, and government clients who cannot afford downtime due to fuel availability.
Cartridge Options
- M10 (10 L) – suited to short-term deployments, maintenance testing, or compact enclosures
- M28 (28 L) – the most common format for security, telecommunications, and monitoring applications
Note: An M28 adaptor is required when using these cartridges with an EFOY Pro fuel cell. This adaptor ensures a secure connection between the cartridge and the fuel cell system. Powerbox supplies these adaptors as part of our methanol accessory range.
Powerbox Tip: Always order an M28 adaptor with your first batch of cartridges. Once installed, the adaptor can be reused for future cartridge changes, ensuring smooth operation and avoiding unnecessary delays.
- MT60 (60 L) – best suited for extended autonomy at remote or hard-to-access sites
All cartridges use a quick-connect coupling system that eliminates spillage risks and ensures that only authorised methanol is used with the EFOY Pro system.
Cartridge Comparison Guide
To help customers match cartridge selection to their application, the chart below shows typical runtime at a 90 W continuous load:
| Cartridge | Volume (L) | Energy (kWh) | Runtime @ 90 W (hours) | Runtime @ 90 W (days) |
| M10 | 10 | 11.0 | 122 hours | 5.1 days |
| M28 | 28 | 30.8 | 342 hours | 14.3 days |
| MT60 | 60 | 66.0 | 733 hours | 30.6 days |
Runtime values are indicative and based on continuous 90 W draw. Actual site autonomy may be longer if load duty cycles are intermittent.
Frequently Asked Questions: EFOY Methanol Supply
Can I use locally produced methanol instead of EFOY cartridges?
No. EFOY Pro systems are direct methanol fuel cells (DMFCs) that require a highly pure methanol formulation. Even trace levels of impurities such as water, lubricants, or denaturants found in industrial methanol can permanently damage the fuel cell stack. For this reason, only EFOY approved cartridges should be used.
I see on SFC Energy’s website that a 5L cartridge (M5) is available. Why do you not stock these?
Yes, an M5 cartridge is available from the manufacturer. However, Powerbox does not stock this format as it is primarily targeted at the caravan and marine markets, not our industrial and critical infrastructure customers. Large order quantities would be required to import this size, making it non-economical to hold. In practice, our customers require longer autonomy, which is why we focus on the M10, M28, and MT60 ranges.
How do I manage methanol logistics for remote sites?
Powerbox works with certified dangerous goods carriers to deliver methanol cartridges to metro and regional locations across New Zealand and Australia. For critical sites, many clients choose to stock additional M28 or MT60 cartridges on-site to extend maintenance intervals.
My system currently uses M28s, but I can only access an M10 or MT60 cartridge. Can I still use this in my installation?
Yes. Any system using a DuoCart Switch (EFOY Pro 2400 / 12000) or Fuel Manager (EFOY Pro 900 / 1800 / 2800) can be configured with different cartridge types. At installation, the cartridge type must be set in the controller menu.
What happens if a cartridge runs empty?
The EFOY Pro will automatically switch to the next connected cartridge if installed in Duo mode. If no cartridges remain, the fuel cell will shut down safely. System monitoring via EFOY Cloud can be used to receive low-fuel alerts before this occurs.
What is the shelf life of methanol cartridges?
Stored in their sealed container, cartridges typically have a shelf life of three years from the date of production. They should be stored in a cool, dry location, away from direct sunlight and ignition sources.
Can I use expired methanol cartridges?
No. Methanol cartridges have defined expiry dates for a reason. Over time, stored methanol can begin to degrade the cartridge material. This may release microscopic plastic impurities into the fuel. If these impurities reach the fuel cell stack, they can cause irreversible damage. While there is some headroom built into the expiry dates, they should be treated as firm limits and always followed.
Why This Matters for Critical Applications
EFOY Pro fuel cells are only as reliable as the methanol supply behind them. By stocking SFC Energy approved methanol cartridges locally, Powerbox provides the certainty that New Zealand customers need when deploying critical off-grid power systems.
From emergency services communications towers to environmental monitoring stations and deployable security platforms, Powerbox ensures that clients receive not just the hardware, but the secure and compliant fuel logistics required to keep these systems running.
