Abstract

The invention relates to a photocatalytic hydrogen production system and a gas production measuring method. The photocatalytic hydrogen production system comprises an inert gas source, a photocatalytic reaction device, a gas collecting, discharging and measuring device, a gas detection and verification device and a main valve control pipeline, wherein the main valve control pipeline is connected with the inert gas source, the photocatalytic reaction device, the gas collecting, discharging and measuring device and the gas detection and verification device sequentially, a hydrogen fuel cell is arranged in the gas detection and verification device, and the hydrogen fuel cell is electrically connected with a load. Two ends of the hydrogen fuel cell are also respectively connected with a voltage display gauge. By adopting the photocatalytic hydrogen production system, the integration of the photocatalytic reaction, the gas production measurement and gas detection and verification can be realized; the gas measuring and detection method is simple, visual and effective; the operation difficulty is lowered, and the maintainability is improved; the product cost, the maintenance cost and the running environment cost can be greatly reduced.
