A Process for manufacturing a porous body, in particular suitable as a membrane, e.g. for use in a fuel cell, is described. To provide membranes with high inertia having high porosity and big pore diameters the process comprises the following steps: a) pro...

Process for manufacturing a porous body, in particular suitable as a membrane, e. g. for use a fuel cell. To provide membranes with higher inertia, the process comprises the following steps: a) providing a thin substrate having the geometrical base of the ...
