Bioenzymatic Fuel Cells

BeFC develops bioenzymatic fuel cells that provide metal-free, paper-based battery alternatives for miniature low-power devices. The company's technology uses enzymes and paper substrates to generate electricity, offering a sustainable alternative to the 15 billion primary batteries disposed of annually, of which 97% end up in landfills or are incinerated. BeFC's biofuel cells are recyclable, safe, and eco-friendly, powering active sensor tags that harvest, monitor, and transmit data across parameters including temperature, humidity, geo-positioning, shock, and pH. Founded in 2020 and headquartered in Grenoble, France, the company has raised approximately $20.6M in Series A funding. BeFC differentiates itself as the only metal-free energy source for the small battery market, with ISO 9001 certification, applications spanning defence, IoT, medical devices, smart logistics, and partnerships including DS Smith for recyclable paper smart trackers.
