Abstract: Systems and methods are provided for digital check conversion. In one embodiment, a method is provided. The method may include accessing, by a computer, respective check information associated with one or more checks. The method may also include generating, by the computer based at least in part on the respective check information, machine-readable code. Furthermore, the method may include presenting, by the computer, the machine-readable code to a payment device for payment of one or more items.

Abstract: A fuel cell which is producible in high volume with electrolyte, positive electrode, and negative electrode components, which incorporate structure, external electrical connections, internal fuel feed passages, fuel distribution passages, oxidizer feed passages, oxidizer distribution passages, return passages, and exhaust passages to form a simple assembly which can be formed into a stack. The fuel cell can utilize either a rigid or flexible electrolyte.

Abstract: A fuel cell which is producible in high volume has electrolyte, positive electrode and negative electrode components which incorporate structure, external electrical connections, internal fuel and oxidizer distribution and an exhaust passage to form a simple assembly which can be formed into a stack. The fuel cell can utilize either a rigid or a flexible electrolyte. The components are manufacturable by a process of printing rolled or flat stock, cutting where appropriate and stacking into a fuel cell assembly.
