  • Publication number: 20250140877
    Abstract: A fuel cell system, e.g., of a motor vehicle, includes a fuel cell stack having fuel cells and non-repeating hardware components, the latter including wet and dry end units. The cells are positioned between the end units. The dry end unit includes an end plate and a compression plate assembly that uniformly compresses the cells against the end plate, and a terminal plate surrounded by a seal plate. An insulator frame disposed adjacent to the compression plate assembly is engaged with the insulator frame via a frictional interface provided by o-ring compression seals having a respective post connected to the terminal plate and the seal plate, and a pocket connected to the insulator frame. The post and pocket of at least one of the compression seals together define a fluid passage. One or more shim plates may be disposed between the end plate and insulator frame.

  • Publication number: 20250139828
    Abstract: Aspects of the present disclosure include methods, apparatuses, and vehicles for performing intrinsic calibration of the cameras in the vehicle. A processor may acquire plural images of a target captured by the camera at different locations. For each image, the processor may tone map the image, binarize the tone-mapped image, define a structuring element based on the digital form of the shape of the target, perform morphology on the image to align and calibrate the structuring elements, filter the target and modify each of the other pixels to black, and compile an output image. Based on the calibration, the principal point values may be shifted to account for discrepancies and store calibrated values in each camera.
