About WätaS Fuel Cell Saxony
WätaS Fuel Cell Saxony GmbH in Leipzig specializes in contract manufacturing of components for PEM fuel cells. The company produces bipolar plates made of titanium or stainless steel 1.4404 with wall thicknesses of 50 to 100 µm and active areas of 100 or 400 cm², which are coated with a carbon coating. Capacity includes up to 4 million bipolar plates as well as 4 million 7-layer MEAs (Membrane Electrode Assembly) per year. In addition, the company assembles PEM fuel cell stacks in the power range from 1 kW to 130 kW gross with a capacity of up to 10,000 stacks per year. The portfolio is complemented by toolmaking for mass production, pilot series and prototype manufacturing, the development of catalyst inks with customer catalysts, characterization measurements of fuel cell stacks, and the rental of an in-house test bench. Production and a testing laboratory are available at the Leipzig site; customers come from industries such as fuel cell technology, hydrogen technology, power generation and mobility.
