Abstract:
Flexible fuel cells show great prospects as a power source in wearable devices due to their high efficiency and good reliability. Herein, a wire‐shaped fuel cell is designed by achieving two main breakthroughs; one is the fabrication of the catalyst‐loaded current collector for wire‐shaped electrodes, and the other is the membrane‐free configuration design according to a new fuel reaction mechanism. Successfully, a flexible wire‐shaped membraneless fuel cell ( W FC) is fabricated for the first time by integrating a biscrolled carbon nanotube (CNT)@ Fe 3 [Co (CN) 6 ] 2 cathode and CNT@ nickel particles anode into a silicone tube with a liquid H 2 O 2 fuel electrolyte. The resulting flexible W FC shows an open‐circuit potential (OCP) of 0.88 V and a power density of 6.28 mW cm −2 . Moreover, it can retain the structural integrity and stability under repeated bending deformation. Hopefully, this article will pave the way for the next‐generation reliable wearable electronics.
