Publication number: 20230018748Abstract: Embodiments described herein relate generally to filter assemblies that include filter elements with cross-channel flow having flat and/or folded arrangements for optimized functionality and performance. The filter assemblies may be formed (e.g., shaped, constructed, etc.) using a variety of shapes, angles, configurations, and materials to improve the filtration and cross-channel flow of fluid through the filter media. The filter media may implement a wide variety of patterns (e.g., repeating, origami, rounded, etc.), shapes (e.g., tetrahedral, rhombus, square), and construction (e.g., pleated, integrated, interdigitated, etc.).Type: ApplicationFiled: December 9, 2019Publication date: January 19, 2023Applicant: Cummins Filtration Inc.Inventors: Mark P.

Publication number: 20210046413Abstract: Filter media including one or multiple sheets of filter media, an upstream inlet, and a downstream outlet. A pleat pack can be formed by alternately folding a flat sheet along pleat fold lines with a high media surface density. The flat sheet of filter media may include a separation geometry feature or separation mechanism that maintains a separation distance between adjacent pleats of the filter media. A separation geometry can comprise one or more embossments forming a raised surface, an inlet spacer mesh and/or an outlet spacer mesh positioned between adjacent pleats, and/or an adhesive bead. The upstream inlet receives dirty fluid along a first direction and the downstream outlet discharges clean fluid along a second direction substantially not parallel to the first direction. The filter element defines an angle between the inlet and outlet flow, allowing large dust particles to move out of the media pack due to inertia.Type: ApplicationFiled: May 7, 2019Publication date: February 18, 2021Applicant: CUMMINS FILTRATION IP, INC.Inventors: Ming Ouyang, Christopher E. Holm, Scott W. Schwartz, Matthew Louison, Miao Li, Jeremiah Cupery, Mark P. Adams, Shantanu Sanjay Ghatnekar

Patent number: 9899691Abstract: System and methods for detecting anode contamination in a fuel cell system are presented. In certain embodiments, a high frequency resistance response of a fuel cell system may be measured at a plurality of frequencies. In some embodiments, the rate of change of high frequency resistance response over time may differ at varied frequencies based on an amount of anode contamination in the fuel cell system. Accordingly, systems and methods disclosed herein may compare high frequency resistance responses taken at a plurality of measured frequencies to detect anode contamination and initiate associated recovery procedures in the fuel cell system.Type: GrantFiled: July 23, 2015Date of Patent: February 20, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Donald H. Keskula, Mark P. Adams, Kenneth L. Kaye, Swaminatha P. Kumaraguru, Jingxin Zhang

Patent number: 9806356Abstract: Systems and methods for improving conditions for anion contaminant removal in a cathode of a PEMFC system are presented. A fuel cell system consistent with certain embodiments may include a cathode compartment having a compressor coupled thereto. The compressor may be configured to receive an input cathode gas via a compressor input and supply the input cathode gas to the cathode compartment via a compressor output. The fuel cell system may further include a cathode gas recirculation value coupled to the cathode compartment configured to receive a cathode exhaust gas output and to selectively provide at least a portion of the cathode exhaust gas output to the compressor input. Consistent with certain embodiments disclosed herein, the compressor may be further configured to supply at least a portion of the cathode exhaust gas output to the cathode compartment via the compressor output.Type: GrantFiled: September 24, 2014Date of Patent: October 31, 2017Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Andrew J. Maslyn, Sergio E. Garcia, Balasubramanian Lakshmanan, Mark P. Adams
