Patent ID: 7977009

Claim:
A cell module for a fuel cell, comprising: a hollow-core electrolyte membrane; two electrodes one of which is arranged on an inner face of the hollow-core electrolyte membrane and the other of which is arranged on an outer face of the hollow-core electrolyte membrane; and collecting members that are connected to the respective two electrodes, wherein at least one of the two electrodes includes nano-columnar bodies on which electrode catalysts are supported, the nano-columnar bodies are formed on at least one of the collecting members corresponding to the at least one of the electrodes that includes the nano-columnar bodies, each of the collecting members is formed of at least one conductive fiber, the nano-columnar bodies are each perpendicularly fixed in relationship to a surface of the at least one conductive fiber, and at least part of the nano-columnar bodies are oriented toward the hollow-core electrolyte membrane.
