US 2007/0166603 A1 · Cell module for fuel cell, method for forming cell module, and fuel cell

Abstract

A cell module for a fuel cell according to embodiments of the invention includes a hollow-core electrolyte membrane; two electrodes one of which is arranged on the inner face of the hollow-core electrolyte membrane and the other of which is arranged on the outer face of the hollow-core electrolyte membrane; and first collecting members that are connected to the respective two electrodes. 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 first collecting members corresponding to the at least one of the electrodes that includes the nano-columnar bodies. At least part of the nano-columnar bodies are oriented toward the hollow-core electrolyte membrane.
