A modular power system includes a fuel cell module and a battery module. The fuel cell module has a plurality of fuel cell stacks. Each fuel cell stack includes a plurality of fuel cells. The plurality of fuel cells is arranged in a vertical orientation in one or more planes located above and perpendicular to a chassis of the vehicle. The battery module has a plurality of batteries arranged in one or more battery stacks. The battery module is electrically connected to the fuel cell module. The plurality of batteries is located in one or more planes directly above and parallel to the chassis.

Modular fuel cell power system architecture for hybrid vehicles

The present disclosure relates to systems and methods for optimizing refueling hydrogen in vehicles. Specifically, the present disclosure relates to identifying a refueling station, conducting a safety check on the vehicle based on a distance between the vehicle and the refueling station, switching a power source of the vehicle to only be a battery, swapping an empty or partially filled hydrogen fuel tank on the vehicle with a filled or partially filled hydrogen fuel tank at the refueling station, and switching the power source of the vehicle to include a hydrogen power source.

A filtration system for a fuel cell hybrid propulsion system includes a first stage filter, a second stage filter positioned downstream of the first stage filter, and a third stage filter positioned downstream of the second stage filter and configured to be positioned upstream of a fuel cell system. The first stage filter has first pores with a first mean pore size. The second stage filter has second pores with a second mean pore size. The third stage filter has third pores with a third mean pore size. The second mean pore size is less than the first mean pore size. The third mean pore size is less than or equal to the second mean pore size. The first, second, and third stage filter are structured to filter an airflow prior to being received by the fuel cell system.

A hydrogen storage tank of a vehicle includes a housing defining an inlet/outlet opening, a control assembly extending into the housing through the opening and comprising a plurality of sensors, and a controller configured to receive signals from the plurality of sensors. The controller of the hydrogen storage tank is configured to, in response to a request for a handshake signal, initiate sending the handshake signal, and in response to the vehicle being started, initiate periodically sending data indicating parameter values received from the plurality of sensors.
