PROBLEM TO BE SOLVED: To provide an electrode substrate for a fuel cell which comprises a carbon film structure where the surface other than an open hole is smooth, with a porous structure comprising a fine communicating hole, so that the gas is widely and evenly distributed with no short path while conductivity and heat transmission characteristics are high, with low contact resistance and heat loss at the interface when a battery cell is formed. SOLUTION: The carbon film structure is flexible and rigid and comprises a porous structure containing a fine communicating hole, with the surface except for an open hole being smooth. The metal particle comprising a catalytic function is carried at nano level. So, when used as the electrode substrate for a fuel cell, the surface contact to another layer on an interface becomes possible when laminated, reducing the contact resistance and heat loss on the interface, for wide and even distribution of gas, causing more efficient catalytic reaction. |
