PROBLEM TO BE SOLVED: To provide a nonwoven fabric fiber web, to provide an ion conductive membrane comprising the nonwoven web, and to use the same for a fuel battery. SOLUTION: This nonwoven fabric fiber web comprises a plurality of first amorphous silica fibers oriented in the x-direction, the y-direction and, if necessary, the z-direction, and, if necessary, bound with one or more binder substances. Therein, one or more continuous strands each comprising one or more second amorphous silica fibers are embedded in the nonwoven fiber web. |
