The fuel cell contains a Received 30 March 2013 TiO2 nanotube anode and a platinum cathode. Water was used as the fuel. The anode has a self-organized Received in revised form 3 May 2013 high aspect ratio TiO2 nanotube layer made through electrochemical oxidation of Ti. Photocatalysis and Accepted 9 July 2013 permanent magnetic field excitation experiments were performed. The photoelectrochemical responses Available online xxx of the anode to visible (Vis) and ultraviolet (UV) light were studied to examine the magnetic field effect. The open circuit voltages were 0.0564, 0.1625, 0.1898 a
