A method for emergency starting of a fuel cell vehicle, comprising:

• determining, by a controller, whether a high-voltage converter or a high-voltage battery has failed;
• connecting, by the controller, a battery switch between the high-voltage converter and the high-voltage battery when the high-voltage converter or high-voltage battery has failed;
• stopping, by the controller, operation of the high-voltage converter;
• and
• supplying power from the high-voltage battery to the BOP without conversion in response to connecting the battery switch.

A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

• program instructions that determine whether a high-voltage converter or a high-voltage battery has failed;
• program instructions that connect a battery switch between the high-voltage converter and the high-voltage battery when the high-voltage converter or high-voltage battery has failed;
• program instructions that stop operation of the high-voltage converter;
• and
• program instructions that control power supplied from the high-voltage battery to the BOP without conversion in response to connecting the battery switch.
