Fuel cells that run on glucose could be ideal alternatives to batteries for powering implanted medical devices, such as pacemakers and brain stimulators. But fuel cells alone cannot generate the quick, high-energy pulses such devices need. Researchers have now made a compact power source that delivers such bursts by combining a glucose fuel cell with a supercapacitor (ACS Energy Lett. 2016, DOI: . . .
