Abstract: A deep learning model parallel processing method that is performed by a deep learning model parallel processing device includes loading a deep learning model to a main process by a central processing unit (CPU), partitioning parallelizable parameters included in the deep learning model by the CPU and storing the partitioned parallelizable parameters in a shared memory, calculating partition parameters partitioned from the parallelizable parameters by a sub-process in each of a plurality of graphic processing units (GPUs) while access of the main process to the shared memory is stopped, obtaining a calculation result of the partition parameters from the shared memory by the CPU and outputting the calculation result by the CPU.

Abstract: A fuel cell is provided to include a cell stack in which unit cells are stacked in a first direction, an end plate disposed at the end of the cell stack, and a current-collecting plate disposed between the end plate and the end of the cell stack. The current-collecting plate includes a conductive area having a conductive surface, which is in electrically conductive surface contact with a reaction surface of the end of the cell stack, and configured to collect power generated by the cell stack, and an airtight area having an airtight surface, which is in airtight surface contact with a non-reaction surface of the end of the cell stack, and surrounding the conductive area. The degree to which the conductive surface protrudes toward the end of the cell stack is different from the degree to which the airtight surface protrudes toward the end of the cell stack.

Abstract: An embodiment fuel cell includes a cell stack including a plurality of unit cells stacked in a first direction, a plate disposed at one of two end portions of the cell stack, the plate including a first terminal unit protruding in a second direction intersecting the first direction, a heating element including a second terminal unit engaged with the first terminal unit of the plate in the second direction, the heating element being disposed between the one of the two end portions of the cell stack and the plate, and an insulation part disposed at at least one of the first terminal unit or the second terminal unit, wherein one of the first terminal unit and the second terminal unit includes a pair of male heater terminals protruding in the second direction, and the other includes a pair of female heater terminals.

Abstract: A fuel cell is provided that includes a cell stack having a plurality of unit cells stacked in a first direction. An enclosure is disposed to surround the cell stack and includes an inlet that suctions external air and an outlet that discharges air that has been suctioned through the inlet and has circulated in the space between the cell stack and the enclosure. An insulating member is disposed to extend in the first direction in the space between an outer surface of the cell stack and an inner surface of the enclosure. The insulating member divides the space into a plurality of spaces and has an aperture formed therein to provide communication between the divided plurality of spaces, and an air intake member configured to suction air discharged from the outlet.
