It is possible that the machine is not having the Simscape toolbox installed. To check if it is installed or not, execute the following command in the MATLAB command window -
>>which –all ssc_fuel_cell
Expected Output:
C:\ProgramFiles\MATLAB\R2022b\toolbox\physmod\simscape\simscapedemos\ssc_fuel_cell.slx
If a path is returned, it would mean that the Simscape Toolbox is installed, else the command will throw an error which indicates that the toolbox is not installed. So, retry opening the Model after installing the Simscape Toolbox.
