Energy supply and cooling is a paramount challenge in information technology. Today, air-cooled microprocessors use more packaging pins for power delivery than for communication and a million-fold larger cooler volume compared to the active elements. Redox flow electrochemistry for power delivery and cooling (REPCOOL) triggers a paradigm shift in powering and cooling computers: Liquid redox electrolytes transported through microfluidic chips provide both power and cooling via the same fluidic pathway. Successful application to highly integrated microprocessor stacks requires detailed research in the fields of redox electrochemistry and membrane science, heat and mass transport in forced convective flows as well as cell design and system-level integration. With this concept, the density and energy efficiency of computer systems may be enhanced substantially.

REPCOOL was a 45-month project (01.09.2013 - 31.05.2017) funded by Grant No. 147661 within the Sinergia program of the Swiss National Science Foundation. The project was coordinated by IBM Research and was a collaborative effort between IBM Research, Paul Scherrer Institut, ETH Zurich and USI Lugano.
