The invention discloses a hydrogen supply system of a hydrogen fuel cell, and relates to the field of hydrogen production. The hydrogen supply system of the hydrogen fuel cell further comprises a judgment unit which is used for monitoring the air pressure in a hydrogen supply pipeline, judging whether the current air pressure is abnormal or not, judging whether the air pressure in the next monitoring period is abnormal or not, and marking the position of an abnormal data source; a control unit which is used for calling an output instruction of the output unit to form a corresponding control instruction, namely a pressure reduction instruction or a non-pressure reduction instruction; a pressure reduction unit, wherein when the output unit outputs the pressure reduction instruction, the pressure reduction unit is controlled by the control unit to perform pressure reduction on the hydrogen supply pipeline; by predicting the air pressure change condition in the next period, when the air pressure is about to exceed the limit and is about to be abnormal, pressure reduction treatment can be performed in advance, so safety accidents caused by failure in timely pressure reduction due to overlong pressure reduction reaction time are avoided, and the safety of the hydrogen supply system is improved.
Description
technical field [0001] The invention relates to the field of hydrogen production, in particular to a hydrogen fuel cell hydrogen supply system. Background technique [0002] At the moment when fossil energy is gradually depleted, finding efficient and sustainable clean energy has become the focus of current research. Among them, hydrogen energy has the advantages of high gravimetric energy density, non-polluting and renewable products, and is an ideal clean energy. Based on this, hydrogen fuel cells came into being, known as the fourth generation power generation technology after hydropower, thermal power and nuclear power. Due to its high energy efficiency, no moving parts, low vibration and noise, no pollution of emissions, simple and flexible assembly, etc., it has gradually been used in the fields of vehicle power, ship power, and backup power. [0003] In the hydrogen fuel cell, the core part is the hydrogen supply system. In the existing hydrogen supply system, it is...
