So, using Distinct().ToArray(), we can easily get the distinct values and convert them to array.

string[] matchID = zteBbhRecords.Cast<IZteBbh>()
         .Select(zteBbh => (zteBbh.CombinedMaster as ICombinedMaster)
             .CellId.ToString()).GroupBy(item => item)
             .Where(items => items.Count() > 1)
             .Select(item => item.Key).Distinct().ToArray();
