Why is the fuel cell fuel put the negative?
The cathode, the anode is named according to the redox, the positive pole, the negative pole is named according to the current direction. In the literature on the study of battery materials, the cathode and anode are generally used, and the positive and negative electrodes are commonly used in terms of circuits.
So the direction of the current from the circuit, the electrons from the anode into the circuit. So the anode is the negative pole of the fuel cell.
From an electrochemical point of view, the fuel reacts at the anode, is oxidized, and the fuel loses its electrons.
