Abstract: The invention relates to a waste heat recovery system (3) for an internal combustion engine (1), having a working fluid circuit (19) with a condenser (31) that is also connected to a working fluid cooling circuit (34), and wherein the working fluid cooling circuit (34) has a cooler (35). The invention provides a waste heat recovery system (3) having a working fluid cooling circuit (34) which is improved in comparison to one design of a working fluid cooling circuit (34). This is achieved by the working fluid cooling circuit (34) having a cooler bypass (46). This configuration makes it generally possible for part of the coolant volume flow to be routed past the cooler (35). This is advantageous in particular at low temperatures since otherwise very low pressures arise in the working fluid cooling circuit (34).

Abstract: The invention relates to a fuel cell system comprising:
a fuel cell arrangement having at least one fuel cell and an air inlet,
a feed line connected to the air inlet, a central air filter device which is connected to an inlet of the feed line either directly or via a distributor block, and
a compressor which is located in the feed line and which is designed to suck in ambient air through the central air filter device and to convey said air through the feed line to the air inlet of the fuel cell arrangement. The invention also relates to a decentralized air filter system, which is designed to filter, downstream of the central filter device, air conveyed from the compressor to the air inlet. The decentralized air filter system comprises at least one decentralized air filter device which is located in the feed line between the compressor and the air inlet of the fuel cell arrangement, in the distributor block, or in the central air filter device.-
