To obtain the key for a PEM certificate, you can use the OpenSSL command-line tool to extract the key from the certificate file. First, you can use the following command to extract the private key from the PEM certificate file: ``` openssl rsa -in certificate.pem -out privatekey.pem ``` This command will prompt you to enter the passphrase for the private key if it is encrypted. Once you have the private key in the `privatekey.pem` file, you can use it for your intended purpose. **

To build a PEM fuel cell yourself, you will need materials such as a proton exchange membrane, catalysts (usually platinum), gas diffusion layers, bipolar plates, and gaskets. Additionally, you will require hydrogen and oxygen as fuel sources, as well as an electrolyte solution. It is important to have proper tools and equipment for assembling the components and ensuring airtight seals to prevent leaks. **

The main difference between a PEM (Proton Exchange Membrane) fuel cell and an AFC (Alkaline Fuel Cell) fuel cell lies in the electrolyte used. PEM fuel cells use a solid polymer electrolyte membrane, while AFC fuel cells use a liquid alkaline electrolyte. This difference in electrolyte affects the operating temperature, efficiency, and overall performance of the fuel cell. Additionally, PEM fuel cells are typically more compact and have a faster start-up time compared to AFC fuel cells. **
