FIG. 5 is a side view of an embodiment of a stacked-die processor with an ion-transfer membrane 506 located in the microfluidic volume and co-planar with the first die 532 and the second die 534. In some embodiments, the microfluidic volume 536 between the first die 532 and the second die 534 defines at least a portion of the electrochemical chamber 504. An ion-transfer membrane 506 divides the microfluidic volume 536 and separates the first electrochemical fluid 508 from the second electrochemical fluid 510. In some embodiments, electrodes (not illustrated in FIG. 5) receive the electrical power produced by the ion transfer across the ion-transfer membrane 506, and the TSVs 548 electrically connect the first die 532 and the second die 534 may conduct electricity therebetween.
FIG. 6 is a schematic view of an embodiment of an electrochemical generator system 600 including a heat exchanger 650. In some embodiments, an electrochemical generator system 600 includes a first electrochemical chamber 604 configured to discharge an electrochemical fluid and provide an electrical power to an electrical load (e.g., the processor 624), and the electrochemical generator system 600 includes a second electrochemical chamber 628 configured to receive electrical power from an electrical source 626 (e.g., a power grid or other power source) to recharge the electrochemical fluid 608, 610.
