Abstract: Disclosed is a heat-balance "gas-gas-liquid" three-phase heat exchange system for a fuel cell, comprising a fuel cell stack, an air pipe (1), a hydrogen pipe (2), a deionized water pipe (3), and a heat exchange device (4) provided on the air pipe (1), the hydrogen pipe (2) and the deionized water pipe (3). Air is adapted to the working environment of the fuel cell before entering the fuel cell stack by subjecting the air to compression and then cooling, because compressed air has a temperature higher than the working temperature of the fuel cell stack. High-pressure liquid hydrogen requires multiple stages of decompression before entering the fuel cell stack. Decompressed hydrogen has a temperature lower than the working temperature of the fuel cell stack, and therefore, decompressed hydrogen needs to be heated before entering the fuel cell stack. Heating of the deionized water prevents damage to the fuel cell during a cold start. The heat exchange device (4) is configured to drive the low-temperature hydrogen using the heat from the water and the high-temperature air, adjusting the overall temperature and reducing the waste of heat energy.

Abstract: A game screen recording method and apparatus, and a computer-readable storage medium. The method comprises: when a game program is started and runs in the foreground, triggering an intra-program speech recognition process corresponding to the game program (101); collecting external speech information by means of the intra-program speech recognition process (102); and when an external screen recording request is identified on the basis of the speech information, performing screen recording on foreground display content during a game program running procedure (103). In the solution, speech recognition is performed on an external screen recording request by using an intra-program speech recognition process that is automatically woken up, and screen recording is then performed on a game program that is run in the foreground, thereby greatly simplifying the operation complexity of screen recording, improving the operation timeliness of screen recording, and effectively reducing the interference of screen recording with a normal game operation.
