Abstract
A fuel-cell powered medical fluid processing machine or dialysis machine is disclosed. The machine is intended for remote or rural areas where standard household or utility power is not available or is subject to interruption. The fuel cell is powered by hydrogen or other source of protons, or may instead be powered by methanol or ethanol, such as a direct methanol fuel cell. The fuel cell may be operated directly, as in powering a portable, wearable dialysis device, or may be operated indirectly, to generate and store power in an electric power storage device of the medical fluid or dialysis device. The medical fluid processing machine or dialysis machine may include circuitry allowing for use by household or utility power while also including a fuel cell for use when other power is not available. A catalytic heater may be used to warm the dialysis fluid.
