Metal fuel cell outdoor power supply

What are the advantages of metal-supported solid oxide fuel cells (MS-SOFCs)?

Metal-supported solid oxide fuel cells (MS-SOFCs) own advantages of high performance, fast start-up, thermal cycle stability, easy sealing, and reduced material cost.

Can a fuel cell power supply system be used for underwater applications?

This work proposes a fuel cell power supply system for underwater applications (e.g., autonomous underwater vehicles), where artificial gills, based on a polymer membrane, harvest the required oxygen from the ambient water.

Can a PEM fuel cell provide oxygen?

In this study, we propose a power supply system consisting of a PEM fuel cell with hydrogen stored in a metal hydride container combined with an artificial gill system that provides the oxygen required by the fuel cell and thereby eliminating the need to store oxygen on board.

What is a 12 watt fuel cell?

A 12 Watt fuel cell (H-12 PEM fuel cell) was used. Hydrogen was stored in metal hydride containers (Hydrostik Pro). A solenoid purge valve was used to purge the fuel cell at regular intervals to remove any impurities that may build up inside the fuel cell.

How much power does a fuel cell deliver?

Depending on how low the internal partial oxygen pressure was allowed to fall, the power delivered by the fuel cell was in the range 0.18 – 0.3 W, where the membrane module achieved an oxygen permeate flux of 1.5–2.5 µmol s −1, see also Figures S2–S4 (Supporting Information).

How does a PEM fuel cell work?

A PEM fuel cell generates electrical energy from the reactants hydrogen and oxygen. The hydrogen is stored in a container at low-pressure using a metal hydride alloy that can store and release hydrogen at room temperature, hence combining safety with a sufficiently competitive energy density.
