The hydraulic pressure introduces necessary compression forces to the membrane 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 novel stack design is possible without significant performance losses. Due to its modularity and scalability, this stack design meets the requirements for large PEMFC units.展开更多
