Fuel Cell

Convallis ac quam cursus per habitant ultrices condimentum

Small satellites, drones and UAVs are driving aerospace industry growth. These devices are powered essentially by energy, and current solutions are not enough to meet their demands.

Li-Ion batteries are the most commonly used, but they have an energy density of 200 Wh/kg, which determines the low operation range of electrical cars, the short flight time of drones and the impossibility of flying heavy aircrafts.

On the other hand, green hydrogen is produced by using renewably generated electricity and can be stored directly or be converted into methane, methanol, or ammonia; in liquid or gaseous forms. We are ready for this revolution.

B5tec is developing a complete sustainable micro fuel cell based on microfluidic technology and using methanol (6,000 Wh/kg) as fuel instead of hydrogen. This new device will be able to provide higher energy density than standard batteries.

Environmentally friendly: The fuel cell is recyclable, metal-free and doesn’t emit polluting gases. E-methanol is surfing the wave of green H2 and solving the CO2 problem.

Miniaturization: microfluidic technology allows the production of nanometer-scale fuel cells, which can be integrated into very small devices.

No complexity: The liquid model converts the complex internal structure, typical for gaseous phases, into an easy-to-implement device, without failures nor need for maintenance.

Higher energy density: The combination of methanol and microfluids allows to provide more energy with less weight and achieve more than 10 times higher energy density than Li-ion batteries.

Long-lasting: unlimited life cycle.
