PROBLEM TO BE SOLVED: To provide a fuel battery cell and a fuel battery in which the fuel battery can be made compact by omitting a diffusion substrate on the anode side, the anode (fuel electrode) can be prevented from drying, and the battery performance can be enhanced under easy to dry conditions such as heavy load, non-humidified, or the like.SOLUTION: When the water (produced water) that is produced by electrochemical reaction on the cathode side is back-diffused to the anode side, it is retained at the same part, because a microporous layer 18 has hydrophilicity. |
