In order to set a line break inside a cell, you have to enable Text Wrapping for the cell, and then break the text. The following code snippet illustrates this.

using (ExcelEngine excelEngine = new ExcelEngine())
{
    IApplication application = excelEngine.Excel;
    application.DefaultVersion = ExcelVersion.Excel2013;

    IWorkbook workbook = application.Workbooks.Create(1);

    IWorksheet worksheet = workbook.Worksheets[0];

    //Save the line break inside the cell

    worksheet.Range["A1"].CellStyle.WrapText = true;

    worksheet.Range["A1"].Text = String.Format("Hello\nworld");

    workbook.SaveAs("LineBreak.xlsx");
}
Using excelEngine As ExcelEngine = New ExcelEngine()
    Dim application As IApplication = excelEngine.Excel
    application.DefaultVersion = ExcelVersion.Excel2013

    Dim workbook As IWorkbook = application.Workbooks.Create(1)

    Dim worksheet As IWorksheet = workbook.Worksheets(0)

    'Save the line break inside the cell

    worksheet.Range("A1").CellStyle.WrapText = True

    worksheet.Range("A1").Text = String.Format("Hello" & vbLf & "world")

    workbook.SaveAs("LineBreak.xlsx")
End Using
using (ExcelEngine excelEngine = new ExcelEngine())
{
    IApplication application = excelEngine.Excel;
    application.DefaultVersion = ExcelVersion.Excel2013;
    IWorkbook workbook = application.Workbooks.Create(1);

    IWorksheet worksheet = workbook.Worksheets[0];

    //Save the line break inside the cell

    worksheet.Range["A1"].CellStyle.WrapText = true;

    worksheet.Range["A1"].Text = String.Format("Hello\nworld");

    //Initializes FileSavePicker
    FileSavePicker savePicker = new FileSavePicker();
    savePicker.SuggestedStartLocation = PickerLocationId.Desktop;
    savePicker.SuggestedFileName = "LineBreak";
    savePicker.FileTypeChoices.Add("Excel Files", new List<string>() { ".xlsx" });

    //Creates a storage file from FileSavePicker
    StorageFile storageFile = await savePicker.PickSaveFileAsync();

    //Saves changes to the specified storage file
    await workbook.SaveAsAsync(storageFile);
}
using (ExcelEngine excelEngine = new ExcelEngine())
{
    IApplication application = excelEngine.Excel;
    application.DefaultVersion = ExcelVersion.Excel2013;
    IWorkbook workbook = application.Workbooks.Create(1);

    IWorksheet worksheet = workbook.Worksheets[0];

    //Save the line break inside the cell

    worksheet.Range["A1"].CellStyle.WrapText = true;

    worksheet.Range["A1"].Text = String.Format("Hello\nworld");

    FileStream stream = new FileStream("LineBreak.xlsx", FileMode.OpenOrCreate, FileAccess.ReadWrite);
    workbook.SaveAs(stream);

    workbook.Close();
    excelEngine.Dispose();
}
using (ExcelEngine excelEngine = new ExcelEngine())
{
    IApplication application = excelEngine.Excel;
    application.DefaultVersion = ExcelVersion.Excel2013;
    IWorkbook workbook = application.Workbooks.Create(1);

    IWorksheet worksheet = workbook.Worksheets[0];

    //Save the line break inside the cell

    worksheet.Range["A1"].CellStyle.WrapText = true;

    worksheet.Range["A1"].Text = String.Format("Hello\nworld");

    MemoryStream stream = new MemoryStream();
    workbook.SaveAs(stream);

    stream.Position = 0;

    //Save the stream as a file in the device and invoke it for viewing
    Xamarin.Forms.DependencyService.Get<ISave>().SaveAndView("LineBreak.xlsx", "application/msexcel", stream);
}
