A major part of the hydrogen production cost by electrolysis is
energy consumption. Therefore, there is a large potential in
improving the efficicency of the electrolysis in order to make
hydrogen produced this way cheaper.
The strategic development of the WELTEMP is to increase the
operating temperature of the PEM electrolyser.
The energy efficiency will be significantly improved because of the
decreased thermodynamic energy requirement, enhanced electrode
kinetics, and the possible integration of the heat recovery.
To achieve this strategic target,it is critical to develop and improve
fundamental materials such as anodic catalysts, membranes, current
collectors, bipolar plates, and other construction materials.
Technical Approach
Upon the systematic characterization results from work on new
catalysts, new ion conducting polymers and current collectors/bipolar
plates, a selection of the materials will be made for further fabrication
of membrane-electrode assemblies. Single cell tests will then be
conducted on a laboratory level for performance and stability
evaluation of the materials and the feasibility of the MEA fabrication
techniques.
As the final target of the project, a 1 kW prototype PEM electrolyser
will be designed, constructed and tested for demonstration.
A laboratory scale single cell steam electrolyser running at 1 atm,
has already been tested at 120-170oC
