The invention relates to a radial compressor () comprising at least one impeller wheel (), which is driven rotatably in a compressor housing () and has a wheel front side () and a wheel rear side (), the wheel front side () being intended to convey a mass flow () by means of a number of blades (), the wheel rear side () of the impeller wheel () having a blading () by means of which a second pressure distribution () is generated on the wheel rear side () of the impeller wheel () during operation of the radial compressor (), which second pressure distribution counteracts a first pressure distribution () on the wheel front side () in order to reduce an axial force that is to be braced in the compressor housing (). In order to functionally improve the radial compressor (), in particular in respect of a use as air supply device in a fuel cell system, the compressor housing () is designed and is combined with the blading () on the wheel rear side () of the impeller wheel () such that, during operation of the radial compressor (), a cooling air mass flow () is conveyed by means of the blading () on the wheel rear side () of the impeller wheel () in addition to the mass flow conveyed by means of the blades () on the wheel front side ().

The invention relates to a fuel cell system () comprising an air compressor () which is used to compress an air mass flow () that is supplied to at least one fuel cell (), and further comprising a cooling air path (), via which a cooling air mass flow () is branched off from the compressed air mass flow (). The cooling of the air compressor () in the fuel cell system () is further improved by an on-demand control () of the compressed cooling air mass flow ().

Fuel cell system with air-cooled compressor/turbine unit and method

Turbomachine (), in particular for a fuel cell system (). The turbomachine () comprises a compressor (), a drive device () and a shaft (). The compressor () has a rotor () arranged on the shaft (), a compressor inlet () and a compressor outlet (). A working fluid can be delivered from the compressor inlet () to the compressor outlet (). A drive cooling path () for cooling the drive device () branches off at the compressor outlet (). Also proposed is a fuel cell system () with a turbomachine () according to the invention, a method for operating the turbomachine () and a method for operating the fuel cell system ().

A computer implemented method, computer program product, and systems for enabling access of a client device to a remote desktop. The remote desktop is implemented within a remote virtual machine engine () selected from one or more virtual machines running on a virtual host (). A connection management component receiving from the client devicea connection request wherein the connection request is directed to establishing a connection between the client device () and the remote virtual machine engine (). If authorization data associated with the connection request complies with a predefined access data structure and corresponding access rules, the connection management component requests destination data of the remote virtual machine engine (), the destination data allowing to interact with the virtual machine engine () and, in response, receiving the destination data. Then it sends to a proxy service () a session request based on the destination data for establishing a session () with the remote virtual machine engine () through the proxy service () in accordance with the authorization data. It receives from the proxy service () proxy connection data configured to allow the client device to establish a proxy connection () via a wide area network (). The proxy connection data is then sent to the client device () to enable the client device () for establishing the proxy connection between the client device () and the proxy service () over the wide area network () to access the remote virtual machine engine () through the session with the remote virtual machine engine ().
