  "textContent": "A park energy reserve feature for a fuel cell electric vehicle (FCEV) includes detecting a key-off event indicative of a powerdown of the FCEV and, in response thereto, determining whether a set of conditions for enablement of a park energy reserve feature of a fuel cell power system (FCPS) of the FCEV are satisfied, where the FCPS comprises a hydrogen (H2) fuel cell stack that is configured to selectively generate electrical energy for recharging a high voltage battery system of the FCEV. When satisfied, the park energy reserve feature is executed by extending operation of the FCPS to recharge a high voltage battery system to a desired state of charge (SOC) level that includes an amount of reserve SOC for operating the FCEV without the use of the FCPS during a subsequent startup procedure of the FCPS and, thereafter, completing a shutdown procedure of the FCEV.",
