Thehydraulic pressure introduces necessary compression forces to themembrane electrode assembly of each cell within a stack. Moreover, homogeneous cell cooling is achieved by this medium. First,prototypes presented in this work indicate that, upscaling of cells for the novelstack design is possible without significantperformancelosses. Due to its modularity and scalability, this stackdesign meets the requirements for large PEMFC units.}, subject = {Polymer-Elektrolytmembran-Brennstoffzelle}, language = {en} } @article{RostBrodmannŞerbanetal.2012, author = {Rost, Ulrich and Brodmann, Michael and Şerban, Viorel-Aurel and Mutascu, Cristian and Roth, Jeffrey and Zekorn, Bruno}, title = {State of the Art of PEM Fuel Cells with a Focus on a Modular Fuel Cell Stack with Hydraulic Compression}, series = {Scientific bulletin of the "politehnica" university of Timisoara, Romania.

One main research activity at the Westphalian Energy Institute of the Westphalian University of Applied Sciences is the development of PEM fuel cells, for which a range of different materials have been investigated for fuel cell pole plate construction. Whereas graphite is a material which has suitable properties concerning conductivity as well as manufacturing e.g. for milling, stainless steel foils are suitable for economical hydroforming processes. However, with steel coating is necessary to increase corrosion resistance as well as electrical conductivity. A new fuel cell stack design is currently under development using separated single fuel cells with hydraulic cell compression. The advantages of this stack concept are modularity, effective heat exchanging and constant, uniform cell compression which are further described in this work.}, subject = {Polymer-Elektrolytmembran-Brennstoffzelle}, language = {en} }
