Anode leak test implementation
First Claim
1. A system for detecting an anode leak of an anode stream driven in a fuel cell stack of a vehicle at varying pressure levels by a pressure regulator device, wherein the fuel cell stack generates electrical current in response to the anode stream, the system comprising:
- a controller operably coupled to the pressure regulator device and configured to;
store at least one first predetermined control value which is indicative of a first pre-selected pressure level;
generate at least one first operational control value;
control the pressure regulator device to adjust the pressure of the anode stream to reach the first pre-selected pressure level with the at least one first operational control value;
compare the at least one first operational control value to the at least one first predetermined control value; and
determine the presence of an anode leak in the anode stream based on the comparison of the at least one first operational control value to the at least one first predetermined control value.

Abstract
A system and method is provided for detecting an anode leak of an anode stream in a fuel cell stack. The system comprises a controller that stores at least one first predetermined control value that corresponds to a first pre-selected pressure level. The controller generates at least one first operational control value. The controller controls a pressure regulator device to adjust the pressure of the anode stream to reach the first pre-selected pressure level with the at least one first operational control value. The controller compares the at least one first operational control value to the at least one first predetermined control value. The controller determines the presence of an anode leak in the anode stream based on the comparison of the at least one first operational control value to the at least one first predetermined control value.
