Abstract: A porous base layer includes a base layer body stacked on a membrane electrode assembly (MEA), and a protrusion pattern provided on one surface of the base layer body that faces the membrane electrode assembly, the protrusion pattern being configured to define a guide flow path for guiding a movement of a target fluid between the membrane electrode assembly and the base layer body, obtaining advantageous effect of improving performance and operational efficiency.

Abstract: Provided is an apparatus for managing a player with a guard including a sensor sensing a vital information of a player to calculate an injury risk of the player to thereby manage a condition of the player, the apparatus including: a communication unit receiving the vital information from the guard and transmitting the injury risk to the guard; a memory storing a program calculating the injury risk to manage the condition of the player; and a processor connected to the communication unit and the memory to execute an operation implemented by the program, in which the program may include instructions using the vital information and pre-stored vital recovering ability data of the player to calculate the injury risk of the player.
