Tested on r2014a (after brushing the dust off of it).

% Create cell array as is described in the quesiton
Zellprojekte = struct; 
Zellprojekte.Z15 = {'B1', 'A2'; 54, 37; 'CATL', 'CATL'}; 

% Convert numbers to strings (chars)
cellfun(@num2str,Zellprojekte.Z15,'UniformOutput',false)

Result

ans =
  3×2 cell array
    {'B1'  }    {'A2'  }
    {'54'  }    {'37'  }
    {'CATL'}    {'CATL'}

" i just i need to use as a string as the following: ' 54 Ah '"

sprintf('%d %s', 54, 'Ah')
ans =
    '54 Ah'

%d for the integer

%s for the string.
