The photo fuel cell (PFC) is a promising technology for simultaneously converting solar energy and bioenergy into electricity. Here, we present a miniature air‐breathing PFC that uses either BiVO 4 or W‐doped BiVO 4 as the photoanode and a Pt/C catalyst as the air‐breathing cathode. The PFC exhibited excellent performance under solar illumination and when fed with several types of biomaterial. We found the PFC performance could be significantly enhanced using W‐doping into the BiVO 4 photoanode. With glucose as the fuel and simulated sunlight (AM 1.5 G) as the light source, the open‐circuit voltage increased from 0.74 to 0.92 V, the short‐circuit current density rose from 0.46 to 1.62 mA cm −2 , and the maximum power density was boosted from 0.05 to 0.38 mW cm −2 , compared to a PFC using undoped BiVO 4 as the anode.
