hydraulic systems (power transmission) and 

 lubrication for deep submergence applica- 

 tion. A variety of fluid properties were inves- 

 tigated in these tests: Viscosity (temperature 

 and pressure effects on), lubricating ability, 

 effects of contamination, corrosion protec- 

 tion, dielectric properties, dissipation factor, 

 ability to form stable emulsions, material 

 compatibility, volatility and toxicity, com- 

 pressibility and density, chemical stability, 

 fire resistance and cost and availability. 

 From these tests and other sources Table 7.5 

 was derived which provides a ready refer- 

 ence for assessing the applicability of a par- 

 ticular fluid in deep submergence applica- 

 tions. The NSRDC authors caution that a 

 listing of P after a fluid does not constitute 

 endorsement for use, nor does Q constitute 

 condemnation. 



FUEL CELLS 



In 1965 General Dynamics installed and 

 tested an Allis-Chalmers fuel cell in its STAR 

 I (Fig. 7.12). A schematic of the fuel cell used 

 in STAR I is shown in Figure 7.13 and ac- 

 cording to reference (21) it works in the 

 following manner. The basic construction 

 consists of two electrodes separated by an 

 electrolyte (potassium hydroxide). A hydra- 

 zine fuel is admitted to the anode electrode, 

 where it reduces hydroxyl ions in water and 

 releases electrons. The electrons flow 

 through the external circuit to the other 

 electrode (the cathode), where the oxidant is 

 admitted. The electrons are used in the oxi- 

 dant's reaction with water to form hydroxyl 

 ions. Ionic conduction through the electro- 

 lyte completes the electrical circuit and pro-
