fuel cell without a bipolar plate

"The scalable fuel cell without the bipolar plates component is new and innovative: within certain limits and levels, stack current and voltage can be adapted to the application so that the familiar bipolar plate may be omitted. A laminate-based cooling and media module is applied in place of bipolar plates. This allows more freedom in the design of fuel cells, and provides new technical and, above all, economical options previously unimaginable. The overall system benefits if, with equal stack performance, the current is only 80 instead of 250 ampere, for instance, and if a stack voltage of 1000 volts or more is achieved in a local high-voltage grid. This results in lower costs for the fuel cell peripherals (NT or HT-PEM), conductors, converters and actors (electric machines, for example). Parasitic losses are minimised: depending on fuel cell design, an almost stoichiometric operation is made possible when the lower cost of operation is the goal. According to the state of technology, base and volume of a stack amount to approximately 70 per cent of a system. The product (stack) was designed for serial production. Only reliably functioning technologies using stable and robust processes are used. Fuel cells and electrolyser stacks can be produced on one production line, for mobile and stationary applications."
