PROBLEM TO BE SOLVED: To provide a fuel battery which is high in installation stability, and has a high power generation quantity by using a member with good workability for a battery.SOLUTION: A fuel battery according to the present invention comprises a battery member. The battery member includes a first carbon nanotube of 100 nm or more in average diameter, and a second carbon nanotube of 30 nm or less in average diameter. The battery member has a structure in which the second carbon nanotube sticks to the surface of the first carbon nanotube, and the second carbon nanotube extends over pieces of the first carbon nanotube.SELECTED DRAWING: Figure 1 |
