WHY – The Challenge.
The solution was conceived for the development and production of components for hydrogen fuel cells. The basis for this is formed by membrane electrode assemblies (MEA) for fuel cells and electrolysers. This involves up to seven extremely thin layers that meet specific customer needs thanks to the various the various compositions of materials. Put together in what is known as a stack, they form the core of a fuel cell. The production of MEAs must take place under controlled clean room conditions in order to ensure consistent product quality.
HOW – The Idea.
The MEAs are produced under clean room conditions in accordance with ISO EN 14644-1 particle purity classes ISO 7/8. However, in the production process, there are sub-areas with higher requirements. Here, mini-environments that completely shield the sensitive areas in the production chain from the environment are used. In accordance with ISO EN 14644-1, they guarantee particle purity classes ISO 5/6 as well as small tolerances with regard to temperature (± 1 K) and humidity (± 3 % r.h.). This reduces costs and allows valuable resources to be used with precision.
WHAT – The Solution.
The complete solution consists of a clean room with integrated mini-environment, ventilation and air-conditioning technology with dryer as well as the customised intelli.4 control system. The controller ensures that the respective conditions are maintained in the complete system and that it works in a particularly efficient and energy-saving manner.
Product selected: Air-conditioning unit Vindur® Compact
In order to reduce energy costs even further, air-conditioning is mainly provided using recirculated air with a proportion of outside air. Fresh air is only supplied to the extent required for personnel and the room pressure. This saves resources and still guarantees the high quality requirements.
