Our proprietary solid acid fuel cell technology enables lower cost of ownership compared to other small generation sources.
Existing technologies
Combustion-based generators are widely used for portable and remote power sources. They operate on widely available fuels, are controllable, low-cost, and ubiquitous. But they are hot, noisy, dirty, inefficient, and require frequent servicing.
Fuel cells have long been lauded for their high efficiency, quiet operation, and low emissions. But depending on the type of fuel cell, they too can face a number of challenges.
Broadly speaking, there are two distinct types of fuel cells:
Hot fuel cells (operate at 500-1000 °C)
Highly efficient, up to 60 per cent electrical efficiency
Tolerant of different fuels and impurities
But require exotic, expensive, and delicate materials to withstand high temperature operation
Cold fuel cells (operate at 20-120 °C)
Ideal for stop/start operation
Very low emissions when using hydrogen
But they often have complex systems and require ultra-pure fuels.
SAFCell Advantages
SAFCell technology is the ideal combination of existing technologies:
Fuel flexible
SAFCell fuel cell stacks can operate on a number of different fuels. Unlike cold fuel cells, our fuel cell stacks are tolerant of impurities. We can operate on industrial grade fuels such as methanol and propane – we don’t require ultra-pure fuel sources. We can also utilize the same fuels as hot fuel cells and combustion-based generators.
Rugged
Operating at mid-temperatures, SAFCell products don’t use delicate materials (e.g. ceramics and glass seals) found in high-temperature fuel cells. Inexpensive metal components and flexible polymer seals enable a low-cost and rugged platform.
Lightweight
Because of our simple system design, we avoid the weight and bulk of other power generation technologies. Hot fuel cells require bulky high-temperature insulation. Cold fuel cells have complex water and/or fuel processing systems. Our military customers demand a compact and lightweight design.
Low maintenance
Fuel cells are solid state devices. They have virtually no moving parts, so this means fewer parts that wear out. Internal combustion engines often require servicing every few hundred hours. Low-maintenance operation is essential for operation in remote environments.
Low emissions
Power that’s cool, clean and quiet is essential for covert operations and sensitive environments. Unlike combustion-based generators, SAFCell products are clean and virtually silent. There is no loud exhaust, no vibrations, and no toxic exhaust fumes.
Low-cost
SAFCell delivers a lower total cost of ownership for customers, through a number of advantages:
Simple system – fewer components
Low-cost components – avoiding expensive materials
Fast & easy installation – rugged design reduces the need for specialized mounting and enclosures
Fuel flexible – uses inexpensive and widely available industrial fuels
Fuel efficient – uses less fuel
Low-maintenance – extended operation with minimal servicing.
