Abstract
Some embodiments of the present invention provide a system and method that incorporates a call to an alarm recovery sequence into a safety system for use within a fuel cell testing system. In other embodiments of the present invention there is provided a safety system and method, for use within a fuel cell testing system, which is able to suspend a fuel cell testing trail and initiate an alarm recovery sequence upon detecting that a corresponding alarm threshold has been violated. The safety system and method is then able to restart the trail if it is determined that the alarm recovery sequence was successful, in that the process and operating parameters that violated the particular alarm threshold have been brought back to within a safe operating range.
Claims23
A fuel cell testing system comprising:
- a safety system for monitoring at least one process and operating parameter during a fuel cell testing trial and evaluating whether at least one alarm threshold has been violated by the at least one process and operating parameter;
- a computer usable medium having computer readable code means embodied therein for causing the safety system to suspend the fuel cell testing trial when said at least one alarm threshold has been violated and subsequently to initiate a corresponding alarm recovery sequence for a violated alarm threshold;
- and
- instructions for recording and evaluating measured process and operating parameters in order to determine whether said at least one alarm threshold has been violated.
A method of controlling a fuel cell testing trial comprising:
- measuring at least one process and operating parameter of a fuel cell under test;
- evaluating the at least one process and operating parameter to determine whether at least one alarm threshold has been violated by said at least one process and operating parameter;
- suspending the fuel cell testing trial if at least one alarm threshold has been violated;
- and
- initiating an alarm recovery sequence.
