Long-term heat-resistance and electrical conductivity of materials in cathode and anode environments of fuel cells
The time dependences (up to 1000 h) of oxidation resistance and surface electrical conductivity characteristics of stainless steels and α- and pseudo α-titanium alloys during holding at 600°C in air and wet hydrogen (H2 + 30 vol.% H2O) were compared. It is confirmed that these characteristics are lower in the anodic environment of fuel cells compared to the cathodic one. It is found in terms of these characteristics that the studied titanium alloys are inferior to stainless steels, especially 316L steel, which, in particular, seems to be related to their tendency to hydride formation.
