Methanol Fuel Cell

The XX55™ reformed methanol fuel cell is the industry’s newest ultra compact and highly portable fuel cell.  The XX55 is designed to meet the rugged off-grid power needs of performance-demanding military and commercial users.

The fuel cell is powered by ultra clean, biodegradable methanol, providing quiet, nearly emission-free operation.  The system is the size of a typical hardbound book and four times lighter and six times smaller than the nearest production portable fuel cell system in its power class.

Scaled from UltraCell’s award-winning and field-proven XX25™ fuel cell system, the XX55 delivers 50 Watts of continuous power and up to 85 Watts of peak power.  It can run continuously off the grid for up to two weeks with a single hot swappable fuel tank.  Its small size makes it inconspicuous, while its long life means that no servicing trips are needed for highly remote or covert surveillance applications.

The XX55 is ideal for a wide variety of higher-power electronic applications including radio and satellite communication gear, remote or mobile surveillance systems, laptop computers and battery charging.

  • UltraCell Reformed Methanol Fuel Cell (RMFC) technology does not contain materials which are damaged at temperature extremes
  • Only UltraCell’s unique RMFC chemistry allows for a single fuel mixture which operates from - 30°C to + 50°C unlike other technologies which require desert and winter fuel mixtures
  • Only UltraCell fuel cells can be stored in OFF mode between - 30°C to + 80°C without artificial heating unlike other technologies which require complex heating kits for storage below 0°C
  • Only UltraCell fuel cells can startup from a - 20°C cold soak without additional thermal kits
  • Autonomous operation with sleep mode functionality
  • Safe for indoor and in-vehicle use: Emissions meet OSHA standards
  • Reduces weight: 70% or more weight savings for a 72 hour mission
  • Industry-leading performance: Operates at high-altitude and cold temperatures
  • Operates anywhere: Quiet, rugged design for jungle, desert, and arctic environments
  • Extended runtime: Hot swappable cartridges and optional long runtime external fuel tanks
  • Simplifies logistics: Powers different devices at different voltages with application-specific tethers
  • Unique hybrid battery system: Delivering 50 watts of continuous power and up to 85 watts peak power
  • Unique clip-on and clip-off battery module design: Enables the use of a wide range of off-the-shelf batteries
