    Abstract: A separator for the stainless steel and the fuel battery which this stainless steel is manufactured with this stainless steel is provided by increasing corrosion resistance using the new the alloy design concept. A stainless steel with a superior corrosion resistance and electric conductance contains austenite type containing the chrome(Cr) with 18~35 weight%, and ferrite-based or tungsten(W) of 4~12 weight% is included in the duplex group stainless steel. The corrosion resistance at the acid solution and electric conductance is excellent, additionally add the component showing the tungsten bronze phenomenon.
