Problems solved by technology
Therefore, there is a problem that it is difficult to provide a straight pipe to connect the air control valve and the humidifier, and the pipe for connecting the air control valve and the humidifier is inevitably in a curved shape (for example, S shape)
As a result, there is a problem that it is difficult to reduce the distance between the fuel cell stack and the humidifier to a certain extent or more, and the degree of freedom in design and space utilization become poor
[0014] In addition, since the pipe for connecting the air control valve and the humidifier is formed in a curved shape in the prior art, there are problems of complicated structure and manufacturing process, and there is a disadvantage in terms of cost, and the pressure difference of the humidifier is due to the curvature and worse energy efficiency (increased power consumption)
[0015] In addition, in the prior art, in order to secure the distance between the fuel cell stack and the humidifier, it is necessary to mount the humidifier on the system frame by using a separate bracket, which causes problems of increased manufacturing cost and increased weight.
[0016] Therefore, various types of research have been conducted in recent years to minimize the space between the fuel cell stack and the humidifier and improve space utilization and design freedom, but the results of the research are still insufficient.
