MicroCell is a micro fuel cell technology that produces electrical energy using formic acid. It provides several times the capacity of conventional batteries in an environmentally friendly way while reducing weight. Due to its compact design, small size and scalability, the technology can be applied across various markets, with immediate potential seen in drones and batteries for power tools. In these applications, MicroCell can increase range, facilitate work and extend operating time without interruptions.

Problem
Professional users of power tools, such as construction and horticulture workers, face limitations with conventional batteries: long charging times, low energy capacity, heavy weight and negative environmental impact. These issues reduce productivity and complicate fieldwork. Despite the growing need for mobile and sustainable solutions, there is still no fast, scalable and environmentally friendly power solution available.
Solution
Our solution is micro fuel cells that use formic acid as a high-energy-density fuel (1750 Wh/L). Each fuel cell has a voltage of 0.6 V, and the required operating voltage is achieved by connecting cells in series. Unlike hydrogen systems, which require tanks under 800 bar, our technology allows safe and compact energy storage. Compared to lithium-ion batteries (150–250 Wh/L), MicroCell batteries can be significantly lighter for the same energy output or offer much higher capacity and autonomy.
