This paper presents construction details of the commercially available uninterruptible power supply system (UPS) in which the PEM fuel cell stack was applied as the primary energy source. Results of components testing as steady state performance of the fuel cell stack used are presented and analyzed in the context of project assumptions. Finally, the results of field tests of the complete UPS unit are presented and analyzed. The designed and constructed uninterruptible power supply with fuel cell module can power any electrical devices up to 300 W for 80 minutes with 33 gram of stored hydrogen.

Within the framework of a project between the University of Magdeburg and the Electrotechnical Institute of Wroclaw, material compositions for electrodes and electrolytes which make possible fuel cell operation at a temperature of approxomately 600°C and, moreover, have low production costs will be developed. The exploration of new electrolytes as well as the prototyping of test cells is being undertaken by the Electrotechnical Institute. The test as well as the investigations of the performance of the cells is made in a specially developed testing procedure and test bench. During the installation and enlargement of a PEM-fuel cell test bench at the University of Magdeburg extensive experience was gained. These experiences can now be used for the design of a small SOFC-test bench. The paper gives an overview on the development of the test bench, the electrolytes and initial results.
