Abstract: A method for preparing a surface modification coating of metal bipolar plates is disclosed, which comprises the following steps: providing a substrate; pre-treating the substrate by processing the substrate, depositing a Ni-layer on the substrate, or a combination thereof, to form an activated layer on the surface of the substrate; packing the substrate in a powder mixture containing a permeated master metal, an activator, and filler powder; and heat-treating the packing to allow the permeated master metal to diffuse into the activated layer and then to form a surface modification coating. The permeation rate of the permeated master metal can be increased due to the activated layer having a high defect concentration. Hence, it is possible to prepare a surface modification coating at a low temperature. The surface modification coating of the present invention can also decrease the interface contact resistance between the bipolar plates and gas diffusion layers.

The permeation rate of the permeated master metal can be increased due to high defect concentration of the activated layer. Hence, a corrosion-resistant surface modification coating is prepared at a low temperature, and it can decrease the interface contact resistance between the metal bipolar plates and gas diffusion layers.

Abstract: A testing method of baseboard management controller (BMC) is used for testing firmware stability of a BMC in a server. The testing method includes initializing a plurality of virtual operating systems; setting a plurality of virtual intelligent platform management interfaces (IPMIs) and a virtual BMC in the virtual operating systems; performing a firmware update on the virtual BMC through the virtual IPMI to update the firmware of the virtual BMC; performing a stability test through the virtual BMC and the server; and loading the firmware of the virtual BMC passing the stability test into a physical BMC.

Abstract: A method for verifying refreshed BIOS content includes the following steps. A virtual machine (VM) is established in a computer waiting for a system BIOS update by the use of a paravirtualization technique. The VM is booted. A new BIOS file content is copied to an address space in a designated range of a memory of a computer host. The computer host is booted with the content of the new BIOS file, and the paravirtual operating system runs on the same hardware platform of the computer host. And, whether the virtual operating system adopting the new BIOS file content runs normally or not is verified to confirm the correctness and safety of the content of the new BIOS file.

Abstract: A cross-subnet-nodes network node device detection method is provided, including the steps of disposing a boot module in each network node devices in an arbitrary subnet of a network; activating the first subnet node device to be a registry server and recording its registry information; activating other network node devices in the subnet, and dispatching the registry information of these devices to the registry server and recording it; searching for the IP address of the first available network node device in the subnet; issuing a command for searching the registry server, issuing a registry information command by the first available network node device, and obtaining the IP address of the registry server and sending it back to the discovery server; and upon receiving a command for searching the network node devices by the registry server, transmitting the information of the node devices in a subnet back to the discovery server.
