PROBLEM TO BE SOLVED: To provide a novel separation membrane for a liquid fuel cell, suitable for a liquid fuel cell, specifically for an alkaline liquid fuel cell.SOLUTION: A separation membrane for a liquid fuel cell has a percolation speed in a cross sectional direction of 40 mol/h g or higher and a pressure resistance between principal surfaces for air of 60 kPa or higher. The liquid fuel cell is preferably an alkaline type. The separation membrane preferably contains a hydrophilic functional group, and the hydrophilic functional group is, for example, a hydroxyl group, a carboxyl group, an amino group, etc. |
