    Abstract: A trigger device for a thermal safety device of a fuel cell automotive system which has a stop, a heat sensitive element consisting of a wire made of shape-memory material, and a trigger abutment is provided. In an intermediate configuration of the trigger device, a distal end of the heat sensitive element is freely slidable by shortening of the heat sensitive element. In an activation configuration of the trigger device, in which temperature perceived by a heat sensitive section of the heat sensitive element is above or equal to an activation temperature, the distal end abuts against the trigger abutment so that a proximal end of the heat sensitive element moves the stop to bring the thermal safety device into a remote emergency configuration.
